Hawaii Five-0 s09e13 Episode Script
Ke Iho Mai Nei Ko Luna (Those Above Are Descending)
1 Feeling alive and I can't complain Sun is out and nothing's in our way No cares, no fears, we're all right Sipping on that summer sunshine Feeling free, so electrified The day is bright and time is on our side - Hey.
-Where's my girl? Good morning to you, too.
Yo! Uncle Steve.
- Steve.
- What's up? What's up? Don't do that.
Don't get up.
Don't get up.
Stay right there.
Oh, hi, hi, hi.
- How you doing? - Good.
- Good.
You look good.
You look good.
- Thank you.
How's Pops doing? Is he looking after you okay while Mom's away? That's a silly question.
Of course I am.
- Whoa, hey.
- What? What's the matter with you? What are you, an animal? - Just want a little piece.
- She's, uh, recovering from a serious accident.
You don't need pancakes.
She needs pancakes.
Sit down and relax.
Eat up, so you can get back in bed.
But I'm not at all tired or hungry.
- Yay! DANNY: Oh, whoa, whoa, whoa, whoa.
Please put the, uh, plate back in front of my daughter, please.
Thank you.
Okay, here's the thing.
Doctor said you got to eat a lot of food, you got to get a lot of rest, and you'll feel like a nice young lady again, you'll feel normal, like a person, so please eat your pancakes.
Okay.
But, Dad, I was actually feeling a little cold.
Could you get me my sweatshirt? Please? You're cold? You don't have a fever or nothing.
All right.
Don't touch her pancakes, you animal.
Please.
You got to do something.
He's driving me crazy.
- It's that bad? - Yeah.
He's all up in my business all day.
Checking up on me, bringing me food.
So much soup.
- Soup? He's doing soup? - Soup.
Matzo ball? Oy, he's like a Jewish grandmother with that stuff.
All right, look, Gracie, here's the thing.
When you were in the hospital, Danno was really upset, of course.
He felt helpless, there was nothing he could do.
He just had to sit there and wait for the news, but now that he's got you back home, he wants to take care of you, you know? And he's gonna do everything he can to get you back on your feet.
He loves you, you know.
- And I love him for that.
- Hmm.
But if you could just get him out of here, even for a few hours.
- Give me one of those pancakes.
DANNY: Hey.
What's the matter with you? Why aren't you eating? Huh? I was waiting for you.
You were waiting for me so you could start eating? - Yeah.
Yeah.
- Eat.
Come on.
You want me to butter your pancakes like you're six? Yeah.
(laughing) (cell phone ringing) You never butter my pancakes.
Yeah.
McGarrett.
Yeah, I'm with him right now.
We'll be right there.
"We"? What's "we"? I need you, buddy.
I just got a homicide.
I'm gonna need you on this one.
I'm so sorry.
Grace, are you gonna be okay if I take him? Aw.
You go.
I'll be okay, but I was really looking forward to spending the day with you, Daddy.
(chuckles) Me, too, Monkey.
Eat, please.
(mouthing): Thank you.
STEVE: So, uh you've been spending a lot of time with Rachel, huh? Yeah.
We're taking care of our daughter who was in a near-fatal car accident.
Uh-huh.
I'm just saying, this whole, uh, this whole "playing house" thing, wondering how much it's got to do with Rachel as well as Grace.
What's going on there? I Nothing's going on.
I mean, we don't want to kill each other for the first time in a long time.
Is that is that all right with you, or? Yeah! Yeah, yeah, yeah.
I-I'm just wondering if you've thought about, maybe, what the plan is, you know? No.
No, no.
No plan.
It's not, uh it's not like a special op, you know what I mean? There's no no specific plan.
So it's just, it's, uh, freestyling, you're freestyling, like, relationship jazz? DANNY: Yeah, I'm basically Miles Davis.
Noelani, good morning.
Commander McGarrett, Detective Williams.
DANNY: Glad I didn't let you eat those pancakes.
Why? 'Cause of him? Oh, I don't have a weak stomach like you.
Uh, sorry.
What do we know so far? John Doe.
Couple surfers found him this morning.
Throat was slashed.
My stethoscope camera indicated no water in the lungs, which means he was dead before he hit the water.
No, I don't think this guy was killed and thrown in the ocean; I think he was killed at the bottom of the ocean.
- Really? Commander McGarrett's right.
The internal bleeding and marbling of the skin are signs of sudden and massive decompression.
DANNY: Decompression.
So, like, he came up too quick and got the bends? Exactly.
The rapid change of pressure causes the nitrogen in the body to separate, forming bubbles in the blood, wreaking havoc on the internal organs.
It's like when you shake up a bottle of soda and then remove the cap.
This guy literally exploded from the inside.
STEVE: And decompression-- or rather a lack of decompression-- this severe means this guy had to have been deep.
I mean, at least 150 feet plus, and he had to have stayed there for a prolonged period of time.
DANNY: All right, so where's his dive gear? I mean, the guy looks like he's ready for his shift at Banana Republic.
That's a really good point.
The guy's not wearing any dive gear, so what was he doing on the bottom of the ocean? [Hawaii Five-O theme song plays.]
Hawaii Five-O 9x13 Ke Iho Mai Nei Ko Luna ( Hey, what are you doing? Hey! (hammering continues) I guess Mom didn't tell you I was coming over.
She told me you might need a hand with this deck.
- Wrong.
- Are you sure? 'Cause it looks like nothing's changed since the last time I was here at Thanksgiving.
You brought the wrong wood.
It's red cedar.
It'll last longer.
Sure.
It'll take me days to power-wash and re-coat every year, but that's not your problem, is it? You're never here, anyway.
- I'm here now.
- Hm.
Yeah, until you make up some excuse to go run off.
You and your, uh, busy schedule.
All right.
You know what, Dad? This time, I don't need an excuse to leave.
You're enough.
Victim's name is Jason Kamaka.
He was a professor of oceanography at Oahu State.
That is until three months ago, when he took a leave of absence to work on this project.
The Neptune One.
It's a deep-sea research lab.
Okay, well, now we know what our victim was doing on the bottom of the ocean.
Oof.
I thought my commute was bad.
The Neptune's crew is six weeks into a two-month mission, and they are studying the effects the Kilauea's lava flow has on marine ecosystems.
Everything was put together by this guy.
DANNY: Who's he? ADAM: Claude Nostromo.
Guy made his fortune in database software and cloud engineering systems.
Now his company has interests in everything from rockets to hydrogen fuel to the Neptune One.
This thing's on the bottom of the ocean, completely cut off from the outside world, which means our victim had to have been killed by one of four people, no? TANI: So you're saying that this murder could've been over lava research? I don't know.
Maybe.
I don't know what it was over.
But here's the thing.
There are some other factors to take into consideration.
I mean, these guys are in serious close quarters for long periods of time.
That can make anybody crazy.
Plus, you got the depth factor and what that does to the brain.
Something called high-pressure nervous syndrome.
I'm talking about paranoia, hallucinations, delusions.
Before you know it, you got a highly combustible situation down there.
CLAUDE: This is unbelievable.
I mean, with projects like this, y-you make contingencies for every possible situation.
Truly, I never could've imagined that DANNY: Murder.
Yeah, that's a crazy one.
STEVE: Mr.
Nostromo, when was the last time you heard from the Neptune One? - We lost contact 12 hours ago.
- I'm sorry, 12 hours? No, I mean, it's Because of the depth, it's not uncommon to go several hours without contact, but usually the comms are restored relatively quickly, which is DANNY: I mean, given the circumstances, uh, your communication problem's probably not a coincidence, right? STEVE: Somebody just killed Dr.
Kamaka, so it's feasible that the person responsible cut communication channels to keep things quiet down there.
Do you know anybody down there who had a beef with him? No.
All of these scientists, I mean, underwent a robust vetting process.
STEVE: Well, of course, but that vetting process goes out the window if somebody's suffering from high-pressure nervous syndrome, no? The ocean it's our last great frontier.
I mean, 95% of it is still unexplored.
And with all great pioneering ventures, there's gonna be risks, but there's no way of truly knowing how someone will respond to that pressurized environment until they're down there.
I agree.
I agree.
Anyway, first things first.
We're gonna need the personnel files of everybody down there, please.
Sure.
Of course, of course.
Um Now, if you'll excuse me, uh, I need to get on top of this.
Hey, Gina? Will you get me Reynolds? Does Reynolds have the files that we need, or? GINA (over intercom): Sir, I have Mr.
Reynolds for you.
Gina, just hold a second.
Thank you so much.
- Excuse me? - I have a crisis to manage.
I have to deploy a sub with a salvage-rescue team.
Plus, I need to formulate a PR response so I can get ahead of this story.
Excuse me, Mr.
Nostromo.
I think you're missing the real crisis here.
I mean, the best-case scenario is that is that Dr.
Kamaka is the only victim, but we're not gonna know that until we get down there.
Down there? Yes, sir.
Until we get down there to your lab.
Your lab is a crime scene, and everybody down there is a suspect.
TANI: Guys, meet our suspects, the crew of the Neptune One.
Jim Walker, Linda Brady, Marcus Nash and Nina Kane.
All of these people are hand-picked by Nostromo for this mission.
Consider them, like, the dream team of oceanographers and scientists.
ADAM: And one of them is a murderer.
STEVE: That is our working theory.
So, we are gonna go down there, assess the situation, collect evidence and interview the suspects.
Bad news is the sub only carries three people.
Oh.
Well, I know who I nominate.
Mm.
Danny and I are actually gonna run point on this one from up here.
Oh.
Junior's gonna take lead on this mission.
- And, uh, he's gonna take you two with.
- Okay.
This is our ride down.
It's a three-person, one-atmosphere submersible.
We're gonna need to take our time going down as the sub acclimates us to the higher pressure of the lab, okay? So you may experience some nausea and dizziness, and that's just your body adjusting.
STEVE: Right, the sub is also equipped with a low-frequency antenna, which means you guys should be able to communicate on comms while you're down there.
TANI: What's happening with the Neptune's transmitter? Is that still down? STEVE: It is still down.
Nobody's heard from the Neptune since right before Dr.
Kamaka was killed, which means we don't know what we're walking into, which is why you guys are gonna take these.
Stun guns, I presume.
Yeah.
Cute, right? Like any highly pressurized environment, firearms would be too dangerous.
So, we're gonna take these.
Any other questions? No.
All set.
Without further ado, be safe, and, uh, Junior, don't, uh, do anything I wouldn't do.
Whoa.
Talk about a blank check.
All right.
Hoo-yah.
STEVE: Hoo-yah.
KAMAKA: Anyway, buddy, I hope you're taking care of your mom for me.
Don't get too used to being the man of the house, though, because there's only 7,212 minutes left until I come home.
You better believe I'm counting down every single one.
Love you.
(computer clicking) Jason sent these messages every day, and that was the last one that we got.
Mrs.
Kamaka, first of all, we're very sorry for your loss.
Uh, clearly, your husband was was a dedicated father, too.
The only reason he took that job was to help my son Kevin.
See, he was recently diagnosed with Gaucher disease.
It's a genetic disorder.
There's an experimental treatment, and it's shown positive results for Kevin, but But insurance won't cover it? Nostromo offered three times what Jason was making at the university, and Jason said that it was the only way that we could afford the next round of treatments.
And I begged him not to go, that we'd find another way.
Let me talk to you about Jason for a minute.
During his time on that lab, did he ever mention anything to you about the other people down there? Maybe he had a problem with somebody, maybe he felt in danger at some stage? Mm, he didn't talk much about the work.
I mean, he couldn't.
Nostromo's lawyers had him sign an NDA the size of a phonebook.
And Jason knew that his communications with the surface were being monitored.
But, uh What? The last time we spoke, just, um, yesterday, actually, I could tell he was agitated, and I asked what was wrong.
And what did he say? Just that the job wasn't what he had signed up for.
From the day my son was diagnosed, I've had to face the possibility that I could lose him.
(crying): But I never even thought what my life would be like without Jason here.
He's been my rock, you know? Mrs.
Kamaka, we can't begin to imagine what you and your son have been through.
But I can only assume that you're not ready to give up any time soon.
Okay, well, neither are we.
(filtered breathing) (beeping) Okay, we're good.
We've got three percent oxygen, 80% helium, and 17% nitrogen.
Five suits, five tanks.
That should mean everyone else is still on board.
Where's the welcoming party? Hey! Five-O! Identify yourself! Guys, I saw someone.
ADAM: Is that Kamaka's blood? No, it can't be.
Kamaka was killed over 12 hours ago.
This looks fresh.
JUNIOR: Hey, you! Hand up right now! Get out here.
Move.
It's okay, buddy.
We're Five-O.
We're here to help.
You're Dr.
Walker, right? Did you get him? Please tell me that you got him.
Did we get who? Wh-What happened to you? It was Nash.
He attacked me.
Dr.
Marcus Nash? Where is he now? (panting): I don't know.
I I woke up this morning, and the power was out.
Brady and Kane told me that we'd been sabotaged, that the power and comms were cut, and that Kamaka and Nash were both missing.
So we split up to look for them, and that's when Nash came out of nowhere and he attacked me.
He was out of his mind.
Somehow, I managed to fend him off and get away.
JUNIOR: Do you know why he attacked you? Was it the conditions in here? Was the atmosphere getting to him? No, he was perfectly fine until this morning.
I have no idea what happened.
The guy just snapped.
Wait.
You mean you don't know where he is? He's still out there? TANI: Dr.
Walker, Jason Kamaka's dead.
His body washed ashore this morning.
ADAM: Based on what you're telling us, it seems like Nash was the one who killed him.
Yeah.
Hey, where's the rest of your crew? I don't know.
But we have to help them.
(gasps) Hey.
Easy.
Five-O.
Jim? Hey, hey.
Stop, stop.
Clear.
(straining): Can't breathe She's hyperventilating.
I think it's a panic attack.
You guys have any oxygen? Just the dive tanks, but they're all in the bay.
And with Nash out there, it's not safe.
Did he attack you, too? BRADY: Didn't have a chance.
I locked myself in here.
Kane did the same in her cabin.
But when her panic attack started, she thought she could get to the bay for a tank, but then she saw Nash, so she detoured here.
Guys, this needs stitches.
There's a med kit on that cart.
She needs oxygen.
We have to get her the dive tanks.
All right, listen up.
Adam, I want you to get Dr.
Kane a tank, okay? When you're down there, I want you to contact HQ and request for an evac vessel A.
S.
A.
P.
The rest of y'all are gonna stay in here and keep that door locked.
Okay.
Tani, on me.
Wait, where are you two going? To find Nash.
Clear.
Moving.
Clear.
Why is this hallway so short? (quietly): Do you have the A.
L.
S.
? Yeah.
You looking for blood? No.
Something else.
Fingerprints.
I think there's something behind here.
(beeps) (shouting) (stun gun crackling) (panting) Well, the stun guns work.
Um, Joons.
We got weird-looking stuff in a secret room.
You know how Nostromo said that they were studying the lava flow? JUNIOR: Yeah.
I'm thinking that was a lie, 'cause these aren't lava rocks.
STEVE: All right, Tani.
According to the geologist we spoke to at Oahu State, those rocks that you found, they are a rare earth element called yttrium.
Safe to say Nostromo isn't collecting them because they're shiny and pretty.
GROVER: No, you got that right.
This yttrium's worth more than gold.
And it's a key component for microprocessors, microchips, mobile chipsets.
All things made by Nostromo's company, so he's keeping them pockets nice and fat.
And I'll tell you something else.
China? They have the market cornered on this stuff.
So he's prospecting.
STEVE: You better believe he's prospecting.
And let me tell you something else.
If Nostromo finds his own reserve of yttrium, we're talking about billions of dollars in profits.
Well, ill-gained profits, as it is illegal to mine the waters that are claimed by the State of Hawaii.
So the whole lava flow study, that was just a cover for this illegal yttrium operation? I mean, it would make sense why Kamaka told his wife that the job wasn't exactly what he had signed up for.
GROVER: Yeah, but he wasn't the only one who got misled.
Nostromo gave us his CCTV coverage, all the stuff that was recorded before the comms went out.
Well, what a surprise.
That secret room you found? No footage to be found on there, but you can still see who was going down the hallway.
Same two crew members every night, except, of course, for last night, when we had a new member going down there.
Yeah.
Our victim, Jason Kamaka.
TANI: Hold on, you said two scientists knew about the hidden room? We know Nash was one of them, because we found him in there.
But who was the other one? Care to explain, Dr.
Brady? I I don't know what that is.
Oh, that-that was convincing.
JUNIOR: Yeah.
See, we have video footage of you and Nash walking up and down that hallway every night with yttrium samples.
We also know Dr.
Kamaka found out about that room last night.
So all that's left to sort out is whether Nash acted alone in killing Kamaka, or if you had a hand in that, too.
WALKER: Brady, what the hell are they talking about? Is this true? Nostromo sent me and Nash down here on a different mission than the rest of you.
We were mapping the ocean floor for yttrium deposits.
The samples we collected were supposed to help Nostromo figure out where to mine for it.
Right, and then the mission was compromised when Kamaka found out about it, and then he confronted you.
It was you.
You killed him.
(shouting) BRADY: No, no! I swear.
I I didn't even know he'd found out about the samples.
I didn't kill Jason Kamaka, and neither did Nash.
KANE: She's lying.
I saw Nash with the knife.
He was about to kill Walker.
No, Nash didn't kill Kamaka.
He couldn't have.
He was working with me all night, and I can prove it.
Sit down.
Sit down.
Just hand me that tablet.
Please.
Every evening, we input the mapping data into the system.
We were up all of last night because we finally finished our research.
Nash and I have distinctive log-ins, and every entry is time-stamped, so Wait.
This can't be right.
The data, the maps.
Everything's gone.
The system's been wiped.
Do you expect us to believe that? It's true.
Except, if you and Nash were the only ones who knew about the data, then who else could have erased it? Nostromo.
WALKER: Oh, he's awake.
JUNIOR: Listen up.
What do you mean? Why would Nostromo do that? WALKER: Wait, you're not actually gonna listen to this lunatic, are you? Mm-hmm.
- Be clear.
- To cover his tracks.
When I logged on this morning, the data was gone.
I thought maybe the drives had been corrupted, or that one of us had wiped them accidentally.
Then I realized Kamaka was missing, and it all made sense.
Nostromo was covering his tracks.
If he could have Kamaka killed, then we were all expendable.
TANI: So you're saying that he was gonna kill everybody in the lab? Do you have any idea how much money he put into this plan? If Kamaka threatened to expose it, then having him killed was nothing more than a business expense.
Truth is, with the data mapping nearly complete, Nostromo didn't need any of us anymore.
Just knowing about this made us a liability to him.
Is that why you had that knife? Why you were acting all paranoid? I didn't know who to trust.
I still don't.
A-All I know is that whoever Nostromo sent after Kamaka could be coming for me next.
Joons.
So I still think he's crazy.
Um, but is he maybe a little less so? ADAM: Guys, we're talking about a billion-dollar investment here.
If Nostromo thought that was in jeopardy, I'm not sure there's much he wouldn't do to protect it.
What happened to Dr.
Kamaka is a tragedy, but that doesn't excuse you making wild, baseless accusations.
I'm sorry, base you said "baseless"? Somebody killed him, you understand? And you, you are the one with billions on the line.
I say this fully realizing how it sounds: Do you know how much money I have? It's enough for a thousand lifetimes, and that's living really well.
All you super rich guys are the same.
There's never enough money.
Because if there was, you'd stop at just being regular rich.
Money is just a means to an end.
It's a way to make dreams like the Neptune into reality.
Dr.
Kamaka shared my dreams.
He was a man of science.
He shared my passion for the betterment of humanity.
GROVER: Or you could just cut the crap about the betterment of humanity "Kumbaya" stuff since we already know about the yttrium.
STEVE: Okay, here's the facts.
You were conducting secretive and highly illegal mining operations down there.
The night that Jason Kamaka finds out about it, he's killed, and then somebody goes ahead and wipes all the data.
So, unless you can explain to us who else would be trying to cover their tracks Wait, hold on.
Did you say someone just wiped the drives? GROVER: Here's the part where he pretends to be surprised.
- No.
You don't understand.
There's no backup for that data.
Not in my office, not in the cloud, not anywhere.
What? You really expect us to believe that some tech whiz genius forgot to back up his billion-dollar data? It's by design.
The computers on the lab are air-gapped to prevent them from being hacked, which means that no one can access them remotely, including me.
So if someone wiped those drives, it had to be done down at the lab.
Explain something to me.
Why would anybody else erase that drive? Well, there's only one reason: to keep the data away from me and sell it on the open market.
There are foreign interests who would pay hundreds of millions for it.
Oh, well, easy come, easy go.
Looks like you've been had.
I think I know by whom.
- Go on.
- I have an inside man down there, someone I sent for the sole purpose of keeping an eye on the others.
You know, prevent this exact thing from happening.
We're gonna need a name.
All right.
Bleeding stopped.
No sign of infection, but he doesn't look well.
I think the conditions are getting to him.
All right.
Well, I need you to just keep an eye on him, okay? The evac vessel is an hour out.
(exhales) Uh, I'm not feeling so great myself.
Is this that dizziness you warned us about, as our bodies adjust? Yeah.
Yeah.
Yeah, it has to be.
I mean I mean, we just got here.
But Walker, he he should have adjusted a long time ago.
Unless Huh? What are you doing? I saw you check the air when we got here.
You said it was fine.
Yeah, well, not anymore.
Look.
The oxygen levels are dropping to one percent.
Anything below that is dangerously hypoxic.
So someone tampered with the levels after we got here.
Yeah, but why would you mess with the levels if that means that you're affected, too? ADAM: Except, not everyone's affected.
(door opens) TANI: Guys, McGarrett spoke to Nostromo.
There is a third person who knows about the yttrium.
They also have motive to kill Kamaka.
Hey! (shouting) Stay back.
Against the booths, now! Stay back.
Easy, easy.
Okay, Tani, I want you to contact McGarrett and let him know what's going on.
(panting): We can't.
The comms are down.
We're too far from the sub antenna.
We we got to get to the moon pool.
It's barricaded.
We got to break it.
Ready? On three.
One, two, three.
Again.
Two, three.
Oh, she's taking the submersible.
McGarrett? McGarrett, do you read? No.
Without the sub, the comms are gone.
Yeah, along with our only way off this lab.
Sub's gone.
TANI: I'm guessing whatever Kane's exfil plan was after killing Kamaka changed when we got here.
At which point, taking our sub became her best way off the lab.
It looks like she didn't want anyone getting off the lab, period.
Almost all the oxygen supply is gone.
TANI: Joons, exactly how much breathable air do we have left? Well, if we keep all our activity levels down to a minimum, I'm guessing at least 40 minutes to an hour.
Hey, yo! Hey, I just tried calling you.
We got a problem.
What? The GPS on the sub showed movement, right? So Nostromo's people tried to get in touch with them, and-and nothing.
Th-The comms just stopped transmitting.
Did you try to contact them? Several times, got nothing.
GROVER: Well, sound to me like they've been jacked, which means our guys are down there stranded or worse.
Danny, come with me.
Lou, send me the coordinates of the Neptune to my phone, please.
And how far away is that Coast Guard evac vessel? - I'll hit them up and find out.
All right, tell them me and Danny are gonna meet them at the dive site, and, Lou, tell them to hurry.
Yes, sir.
(rapid beeping) Sorry, what are you looking for exactly? Because unless it's a secret cache of oxygen, I don't see the point in exerting yourself.
This is a transmission buoy.
We can put a message on it, and then we send it up to the surface.
It'll broadcast our SOS to all emergency frequencies.
Joons, by the time someone catches that signal and sends a crew down - I know.
It's a Hail Mary, but it's our best shot.
Mayday.
Mayday.
This is Officer Junior Reigns with the Five-O Task Force in urgent need of assistance.
We are six people stranded on board the Neptune One underwater lab.
At 1605, we have roughly 37 minutes left of usable air.
Lab coordinates, north: 21 degrees, 26 tack 927, west: 157 degrees, 62 tack 179.
Depth of 127 meters.
Please contact the Five-O Task Force.
Please send help.
Over.
Wait, Joons.
I'm gonna go.
Let me go.
No.
Look at you.
You can barely stand up.
You don't look too hot yourself.
(beeps) I'll be back.
(inhales) (device beeping) (coughing) (both panting) (grunts) Thanks.
(pained breaths) - I got disoriented.
- Yeah.
(groans) You can get me dinner when we're out of here.
I want sushi.
Okay? Like, really expensive sushi.
Hey.
I went to go to see my dad this morning.
It sucked.
(panting): I'm sorry.
It's okay.
Turns out that's the best part of my day.
Oh.
(coughs) (Tani panting) DANNY: Slow down a little bit.
Slow down.
The GPS says you're right on top of the lab.
- Stop.
- All right.
There's the Coast Guard boat.
That's good.
They should have a diving bell.
I'll go down with the rescue team.
We don't even know what's going on down there.
- They could be dead, for all we know.
- Hey, hey.
Stop.
Please don't do that.
Okay? I'm anxious, too.
We need to stay positive.
So keep your mind on the rescue and not think like that, please.
(beeping) Is that the phone? GROVER: Hey, it's Grover.
Hey, Lou.
What's up? So, a fishing trawler just picked up an SOS message from Junior.
Somehow, the kid got a transmission out.
My man.
Look, it's bad.
He says they're running out of breathable air.
There's six of them down there.
Down to 37 minutes.
Only, the transmission was recorded at 1605.
That's 31 minutes ago.
They got six minutes' worth of air? Which means, by the time that vessel gets here and launches that evac op, it's gonna be too late.
What are you doing now, Beautiful Mind, huh? I'm doing the math.
We got two dive tanks, they're both 80s, which means we've got 160 cubic feet of trimix, right? Which breaks down to approximately 112 minutes of breathable air.
Divide that by the six people that are underneath this, you got a little over 18 minutes each.
If they take turns, they should be able to ration the air in these two tanks and make it last when the Coast Guard gets here with more air.
That's great, but the tanks are up here, so what I imagine is, you're gonna swim those tanks down there? What, you got a better idea? No.
Call the Coast Guard, tell that vessel they need to be here-- they got 18 minutes to get here and get more air down to these people.
Your math is goofy, okay? You got to use some of the air yourself, you got to go down there, you're gonna leave the tanks, come back up, what about you? What about your air, huh? Danny, the best chance of survival for these guys is if I free-dive these tanks down, okay? Now, I got the weight of the tanks.
It's gonna help get me down there.
Ideally, I'd have some kind of guideline, but I don't.
Why don't you use the anchor? There's no way the anchor's gonna reach 130 meters, Danny.
There's no way you're gonna make 130 meters, either.
Let's just be real for a second.
You go down there, you're gonna have to hit a little bit of air, you know? Then what? How are you not gonna explode when you come back up? I'm gonna exhale all of it on the ascent.
But listen, if I get back to this boat and I look like a potato, you got ten minutes to get me to a hyperbaric chamber, all right? Do me a favor, drag this over here.
Come on.
- Steve - Uh-uh.
No pep talks.
Besides, you suck at them.
Thank you.
(deep breathing) (inhales deeply) (deep breathing) (air hissing) Rescue team, 15 minutes.
I can't stay.
Not enough air.
Understand? Make this last.
I got to go.
Stay calm.
One for the road.
(gasping) Steve! You okay? Huh? Everybody else, they okay? Rescue team? Oh.
They'll be there in ten minutes.
It's all good.
Don't ever, ever do that to me again, please.
Now that I know you can hold your breath that long, I don't want to hear you complain when I bring takeout into the car.
Okay? GROVER: Thank you.
- Hey.
- Hey.
Well, I got some very good news on our murderess, Nina Kane.
What's up? Well, the United States Navy tracked her sub, led us right to her dealer.
Wait a minute, we got her in custody? Oh, no.
No, she's in ICU.
In her haste to surface and collect on her payday, she gave herself the bends.
Wow.
Karma really is a bitch sometimes, huh? We got some good news, too.
Uh, Nostromo is gonna do the right thing and, uh, take care of our vic's kid's medical bills.
STEVE: Even the experimental gene therapy treatments.
Kid's covered for life.
That's the least he can do with his rich ass.
STEVE: Well, and assist the Feds in their investigation of his illegal mining operation.
(door opens) Look who's back from the abyss.
STEVE: Hey.
GROVER: Well, look who survived the decompression.
We did, yeah.
16 hours.
16 hours stuck in a hyperbaric-- I'm sorry, scratch that-- hyper-barbaric chamber with, um, Adam and Joons arguing about what's better, cartoons or anime.
- It's anime.
Oh, cartoons.
Come on.
Help me.
Hey, where's Junior? Junior said he would be in later.
He just has to take care of something first.
Okay.
-Where's my girl? Good morning to you, too.
Yo! Uncle Steve.
- Steve.
- What's up? What's up? Don't do that.
Don't get up.
Don't get up.
Stay right there.
Oh, hi, hi, hi.
- How you doing? - Good.
- Good.
You look good.
You look good.
- Thank you.
How's Pops doing? Is he looking after you okay while Mom's away? That's a silly question.
Of course I am.
- Whoa, hey.
- What? What's the matter with you? What are you, an animal? - Just want a little piece.
- She's, uh, recovering from a serious accident.
You don't need pancakes.
She needs pancakes.
Sit down and relax.
Eat up, so you can get back in bed.
But I'm not at all tired or hungry.
- Yay! DANNY: Oh, whoa, whoa, whoa, whoa.
Please put the, uh, plate back in front of my daughter, please.
Thank you.
Okay, here's the thing.
Doctor said you got to eat a lot of food, you got to get a lot of rest, and you'll feel like a nice young lady again, you'll feel normal, like a person, so please eat your pancakes.
Okay.
But, Dad, I was actually feeling a little cold.
Could you get me my sweatshirt? Please? You're cold? You don't have a fever or nothing.
All right.
Don't touch her pancakes, you animal.
Please.
You got to do something.
He's driving me crazy.
- It's that bad? - Yeah.
He's all up in my business all day.
Checking up on me, bringing me food.
So much soup.
- Soup? He's doing soup? - Soup.
Matzo ball? Oy, he's like a Jewish grandmother with that stuff.
All right, look, Gracie, here's the thing.
When you were in the hospital, Danno was really upset, of course.
He felt helpless, there was nothing he could do.
He just had to sit there and wait for the news, but now that he's got you back home, he wants to take care of you, you know? And he's gonna do everything he can to get you back on your feet.
He loves you, you know.
- And I love him for that.
- Hmm.
But if you could just get him out of here, even for a few hours.
- Give me one of those pancakes.
DANNY: Hey.
What's the matter with you? Why aren't you eating? Huh? I was waiting for you.
You were waiting for me so you could start eating? - Yeah.
Yeah.
- Eat.
Come on.
You want me to butter your pancakes like you're six? Yeah.
(laughing) (cell phone ringing) You never butter my pancakes.
Yeah.
McGarrett.
Yeah, I'm with him right now.
We'll be right there.
"We"? What's "we"? I need you, buddy.
I just got a homicide.
I'm gonna need you on this one.
I'm so sorry.
Grace, are you gonna be okay if I take him? Aw.
You go.
I'll be okay, but I was really looking forward to spending the day with you, Daddy.
(chuckles) Me, too, Monkey.
Eat, please.
(mouthing): Thank you.
STEVE: So, uh you've been spending a lot of time with Rachel, huh? Yeah.
We're taking care of our daughter who was in a near-fatal car accident.
Uh-huh.
I'm just saying, this whole, uh, this whole "playing house" thing, wondering how much it's got to do with Rachel as well as Grace.
What's going on there? I Nothing's going on.
I mean, we don't want to kill each other for the first time in a long time.
Is that is that all right with you, or? Yeah! Yeah, yeah, yeah.
I-I'm just wondering if you've thought about, maybe, what the plan is, you know? No.
No, no.
No plan.
It's not, uh it's not like a special op, you know what I mean? There's no no specific plan.
So it's just, it's, uh, freestyling, you're freestyling, like, relationship jazz? DANNY: Yeah, I'm basically Miles Davis.
Noelani, good morning.
Commander McGarrett, Detective Williams.
DANNY: Glad I didn't let you eat those pancakes.
Why? 'Cause of him? Oh, I don't have a weak stomach like you.
Uh, sorry.
What do we know so far? John Doe.
Couple surfers found him this morning.
Throat was slashed.
My stethoscope camera indicated no water in the lungs, which means he was dead before he hit the water.
No, I don't think this guy was killed and thrown in the ocean; I think he was killed at the bottom of the ocean.
- Really? Commander McGarrett's right.
The internal bleeding and marbling of the skin are signs of sudden and massive decompression.
DANNY: Decompression.
So, like, he came up too quick and got the bends? Exactly.
The rapid change of pressure causes the nitrogen in the body to separate, forming bubbles in the blood, wreaking havoc on the internal organs.
It's like when you shake up a bottle of soda and then remove the cap.
This guy literally exploded from the inside.
STEVE: And decompression-- or rather a lack of decompression-- this severe means this guy had to have been deep.
I mean, at least 150 feet plus, and he had to have stayed there for a prolonged period of time.
DANNY: All right, so where's his dive gear? I mean, the guy looks like he's ready for his shift at Banana Republic.
That's a really good point.
The guy's not wearing any dive gear, so what was he doing on the bottom of the ocean? [Hawaii Five-O theme song plays.]
Hawaii Five-O 9x13 Ke Iho Mai Nei Ko Luna ( Hey, what are you doing? Hey! (hammering continues) I guess Mom didn't tell you I was coming over.
She told me you might need a hand with this deck.
- Wrong.
- Are you sure? 'Cause it looks like nothing's changed since the last time I was here at Thanksgiving.
You brought the wrong wood.
It's red cedar.
It'll last longer.
Sure.
It'll take me days to power-wash and re-coat every year, but that's not your problem, is it? You're never here, anyway.
- I'm here now.
- Hm.
Yeah, until you make up some excuse to go run off.
You and your, uh, busy schedule.
All right.
You know what, Dad? This time, I don't need an excuse to leave.
You're enough.
Victim's name is Jason Kamaka.
He was a professor of oceanography at Oahu State.
That is until three months ago, when he took a leave of absence to work on this project.
The Neptune One.
It's a deep-sea research lab.
Okay, well, now we know what our victim was doing on the bottom of the ocean.
Oof.
I thought my commute was bad.
The Neptune's crew is six weeks into a two-month mission, and they are studying the effects the Kilauea's lava flow has on marine ecosystems.
Everything was put together by this guy.
DANNY: Who's he? ADAM: Claude Nostromo.
Guy made his fortune in database software and cloud engineering systems.
Now his company has interests in everything from rockets to hydrogen fuel to the Neptune One.
This thing's on the bottom of the ocean, completely cut off from the outside world, which means our victim had to have been killed by one of four people, no? TANI: So you're saying that this murder could've been over lava research? I don't know.
Maybe.
I don't know what it was over.
But here's the thing.
There are some other factors to take into consideration.
I mean, these guys are in serious close quarters for long periods of time.
That can make anybody crazy.
Plus, you got the depth factor and what that does to the brain.
Something called high-pressure nervous syndrome.
I'm talking about paranoia, hallucinations, delusions.
Before you know it, you got a highly combustible situation down there.
CLAUDE: This is unbelievable.
I mean, with projects like this, y-you make contingencies for every possible situation.
Truly, I never could've imagined that DANNY: Murder.
Yeah, that's a crazy one.
STEVE: Mr.
Nostromo, when was the last time you heard from the Neptune One? - We lost contact 12 hours ago.
- I'm sorry, 12 hours? No, I mean, it's Because of the depth, it's not uncommon to go several hours without contact, but usually the comms are restored relatively quickly, which is DANNY: I mean, given the circumstances, uh, your communication problem's probably not a coincidence, right? STEVE: Somebody just killed Dr.
Kamaka, so it's feasible that the person responsible cut communication channels to keep things quiet down there.
Do you know anybody down there who had a beef with him? No.
All of these scientists, I mean, underwent a robust vetting process.
STEVE: Well, of course, but that vetting process goes out the window if somebody's suffering from high-pressure nervous syndrome, no? The ocean it's our last great frontier.
I mean, 95% of it is still unexplored.
And with all great pioneering ventures, there's gonna be risks, but there's no way of truly knowing how someone will respond to that pressurized environment until they're down there.
I agree.
I agree.
Anyway, first things first.
We're gonna need the personnel files of everybody down there, please.
Sure.
Of course, of course.
Um Now, if you'll excuse me, uh, I need to get on top of this.
Hey, Gina? Will you get me Reynolds? Does Reynolds have the files that we need, or? GINA (over intercom): Sir, I have Mr.
Reynolds for you.
Gina, just hold a second.
Thank you so much.
- Excuse me? - I have a crisis to manage.
I have to deploy a sub with a salvage-rescue team.
Plus, I need to formulate a PR response so I can get ahead of this story.
Excuse me, Mr.
Nostromo.
I think you're missing the real crisis here.
I mean, the best-case scenario is that is that Dr.
Kamaka is the only victim, but we're not gonna know that until we get down there.
Down there? Yes, sir.
Until we get down there to your lab.
Your lab is a crime scene, and everybody down there is a suspect.
TANI: Guys, meet our suspects, the crew of the Neptune One.
Jim Walker, Linda Brady, Marcus Nash and Nina Kane.
All of these people are hand-picked by Nostromo for this mission.
Consider them, like, the dream team of oceanographers and scientists.
ADAM: And one of them is a murderer.
STEVE: That is our working theory.
So, we are gonna go down there, assess the situation, collect evidence and interview the suspects.
Bad news is the sub only carries three people.
Oh.
Well, I know who I nominate.
Mm.
Danny and I are actually gonna run point on this one from up here.
Oh.
Junior's gonna take lead on this mission.
- And, uh, he's gonna take you two with.
- Okay.
This is our ride down.
It's a three-person, one-atmosphere submersible.
We're gonna need to take our time going down as the sub acclimates us to the higher pressure of the lab, okay? So you may experience some nausea and dizziness, and that's just your body adjusting.
STEVE: Right, the sub is also equipped with a low-frequency antenna, which means you guys should be able to communicate on comms while you're down there.
TANI: What's happening with the Neptune's transmitter? Is that still down? STEVE: It is still down.
Nobody's heard from the Neptune since right before Dr.
Kamaka was killed, which means we don't know what we're walking into, which is why you guys are gonna take these.
Stun guns, I presume.
Yeah.
Cute, right? Like any highly pressurized environment, firearms would be too dangerous.
So, we're gonna take these.
Any other questions? No.
All set.
Without further ado, be safe, and, uh, Junior, don't, uh, do anything I wouldn't do.
Whoa.
Talk about a blank check.
All right.
Hoo-yah.
STEVE: Hoo-yah.
KAMAKA: Anyway, buddy, I hope you're taking care of your mom for me.
Don't get too used to being the man of the house, though, because there's only 7,212 minutes left until I come home.
You better believe I'm counting down every single one.
Love you.
(computer clicking) Jason sent these messages every day, and that was the last one that we got.
Mrs.
Kamaka, first of all, we're very sorry for your loss.
Uh, clearly, your husband was was a dedicated father, too.
The only reason he took that job was to help my son Kevin.
See, he was recently diagnosed with Gaucher disease.
It's a genetic disorder.
There's an experimental treatment, and it's shown positive results for Kevin, but But insurance won't cover it? Nostromo offered three times what Jason was making at the university, and Jason said that it was the only way that we could afford the next round of treatments.
And I begged him not to go, that we'd find another way.
Let me talk to you about Jason for a minute.
During his time on that lab, did he ever mention anything to you about the other people down there? Maybe he had a problem with somebody, maybe he felt in danger at some stage? Mm, he didn't talk much about the work.
I mean, he couldn't.
Nostromo's lawyers had him sign an NDA the size of a phonebook.
And Jason knew that his communications with the surface were being monitored.
But, uh What? The last time we spoke, just, um, yesterday, actually, I could tell he was agitated, and I asked what was wrong.
And what did he say? Just that the job wasn't what he had signed up for.
From the day my son was diagnosed, I've had to face the possibility that I could lose him.
(crying): But I never even thought what my life would be like without Jason here.
He's been my rock, you know? Mrs.
Kamaka, we can't begin to imagine what you and your son have been through.
But I can only assume that you're not ready to give up any time soon.
Okay, well, neither are we.
(filtered breathing) (beeping) Okay, we're good.
We've got three percent oxygen, 80% helium, and 17% nitrogen.
Five suits, five tanks.
That should mean everyone else is still on board.
Where's the welcoming party? Hey! Five-O! Identify yourself! Guys, I saw someone.
ADAM: Is that Kamaka's blood? No, it can't be.
Kamaka was killed over 12 hours ago.
This looks fresh.
JUNIOR: Hey, you! Hand up right now! Get out here.
Move.
It's okay, buddy.
We're Five-O.
We're here to help.
You're Dr.
Walker, right? Did you get him? Please tell me that you got him.
Did we get who? Wh-What happened to you? It was Nash.
He attacked me.
Dr.
Marcus Nash? Where is he now? (panting): I don't know.
I I woke up this morning, and the power was out.
Brady and Kane told me that we'd been sabotaged, that the power and comms were cut, and that Kamaka and Nash were both missing.
So we split up to look for them, and that's when Nash came out of nowhere and he attacked me.
He was out of his mind.
Somehow, I managed to fend him off and get away.
JUNIOR: Do you know why he attacked you? Was it the conditions in here? Was the atmosphere getting to him? No, he was perfectly fine until this morning.
I have no idea what happened.
The guy just snapped.
Wait.
You mean you don't know where he is? He's still out there? TANI: Dr.
Walker, Jason Kamaka's dead.
His body washed ashore this morning.
ADAM: Based on what you're telling us, it seems like Nash was the one who killed him.
Yeah.
Hey, where's the rest of your crew? I don't know.
But we have to help them.
(gasps) Hey.
Easy.
Five-O.
Jim? Hey, hey.
Stop, stop.
Clear.
(straining): Can't breathe She's hyperventilating.
I think it's a panic attack.
You guys have any oxygen? Just the dive tanks, but they're all in the bay.
And with Nash out there, it's not safe.
Did he attack you, too? BRADY: Didn't have a chance.
I locked myself in here.
Kane did the same in her cabin.
But when her panic attack started, she thought she could get to the bay for a tank, but then she saw Nash, so she detoured here.
Guys, this needs stitches.
There's a med kit on that cart.
She needs oxygen.
We have to get her the dive tanks.
All right, listen up.
Adam, I want you to get Dr.
Kane a tank, okay? When you're down there, I want you to contact HQ and request for an evac vessel A.
S.
A.
P.
The rest of y'all are gonna stay in here and keep that door locked.
Okay.
Tani, on me.
Wait, where are you two going? To find Nash.
Clear.
Moving.
Clear.
Why is this hallway so short? (quietly): Do you have the A.
L.
S.
? Yeah.
You looking for blood? No.
Something else.
Fingerprints.
I think there's something behind here.
(beeps) (shouting) (stun gun crackling) (panting) Well, the stun guns work.
Um, Joons.
We got weird-looking stuff in a secret room.
You know how Nostromo said that they were studying the lava flow? JUNIOR: Yeah.
I'm thinking that was a lie, 'cause these aren't lava rocks.
STEVE: All right, Tani.
According to the geologist we spoke to at Oahu State, those rocks that you found, they are a rare earth element called yttrium.
Safe to say Nostromo isn't collecting them because they're shiny and pretty.
GROVER: No, you got that right.
This yttrium's worth more than gold.
And it's a key component for microprocessors, microchips, mobile chipsets.
All things made by Nostromo's company, so he's keeping them pockets nice and fat.
And I'll tell you something else.
China? They have the market cornered on this stuff.
So he's prospecting.
STEVE: You better believe he's prospecting.
And let me tell you something else.
If Nostromo finds his own reserve of yttrium, we're talking about billions of dollars in profits.
Well, ill-gained profits, as it is illegal to mine the waters that are claimed by the State of Hawaii.
So the whole lava flow study, that was just a cover for this illegal yttrium operation? I mean, it would make sense why Kamaka told his wife that the job wasn't exactly what he had signed up for.
GROVER: Yeah, but he wasn't the only one who got misled.
Nostromo gave us his CCTV coverage, all the stuff that was recorded before the comms went out.
Well, what a surprise.
That secret room you found? No footage to be found on there, but you can still see who was going down the hallway.
Same two crew members every night, except, of course, for last night, when we had a new member going down there.
Yeah.
Our victim, Jason Kamaka.
TANI: Hold on, you said two scientists knew about the hidden room? We know Nash was one of them, because we found him in there.
But who was the other one? Care to explain, Dr.
Brady? I I don't know what that is.
Oh, that-that was convincing.
JUNIOR: Yeah.
See, we have video footage of you and Nash walking up and down that hallway every night with yttrium samples.
We also know Dr.
Kamaka found out about that room last night.
So all that's left to sort out is whether Nash acted alone in killing Kamaka, or if you had a hand in that, too.
WALKER: Brady, what the hell are they talking about? Is this true? Nostromo sent me and Nash down here on a different mission than the rest of you.
We were mapping the ocean floor for yttrium deposits.
The samples we collected were supposed to help Nostromo figure out where to mine for it.
Right, and then the mission was compromised when Kamaka found out about it, and then he confronted you.
It was you.
You killed him.
(shouting) BRADY: No, no! I swear.
I I didn't even know he'd found out about the samples.
I didn't kill Jason Kamaka, and neither did Nash.
KANE: She's lying.
I saw Nash with the knife.
He was about to kill Walker.
No, Nash didn't kill Kamaka.
He couldn't have.
He was working with me all night, and I can prove it.
Sit down.
Sit down.
Just hand me that tablet.
Please.
Every evening, we input the mapping data into the system.
We were up all of last night because we finally finished our research.
Nash and I have distinctive log-ins, and every entry is time-stamped, so Wait.
This can't be right.
The data, the maps.
Everything's gone.
The system's been wiped.
Do you expect us to believe that? It's true.
Except, if you and Nash were the only ones who knew about the data, then who else could have erased it? Nostromo.
WALKER: Oh, he's awake.
JUNIOR: Listen up.
What do you mean? Why would Nostromo do that? WALKER: Wait, you're not actually gonna listen to this lunatic, are you? Mm-hmm.
- Be clear.
- To cover his tracks.
When I logged on this morning, the data was gone.
I thought maybe the drives had been corrupted, or that one of us had wiped them accidentally.
Then I realized Kamaka was missing, and it all made sense.
Nostromo was covering his tracks.
If he could have Kamaka killed, then we were all expendable.
TANI: So you're saying that he was gonna kill everybody in the lab? Do you have any idea how much money he put into this plan? If Kamaka threatened to expose it, then having him killed was nothing more than a business expense.
Truth is, with the data mapping nearly complete, Nostromo didn't need any of us anymore.
Just knowing about this made us a liability to him.
Is that why you had that knife? Why you were acting all paranoid? I didn't know who to trust.
I still don't.
A-All I know is that whoever Nostromo sent after Kamaka could be coming for me next.
Joons.
So I still think he's crazy.
Um, but is he maybe a little less so? ADAM: Guys, we're talking about a billion-dollar investment here.
If Nostromo thought that was in jeopardy, I'm not sure there's much he wouldn't do to protect it.
What happened to Dr.
Kamaka is a tragedy, but that doesn't excuse you making wild, baseless accusations.
I'm sorry, base you said "baseless"? Somebody killed him, you understand? And you, you are the one with billions on the line.
I say this fully realizing how it sounds: Do you know how much money I have? It's enough for a thousand lifetimes, and that's living really well.
All you super rich guys are the same.
There's never enough money.
Because if there was, you'd stop at just being regular rich.
Money is just a means to an end.
It's a way to make dreams like the Neptune into reality.
Dr.
Kamaka shared my dreams.
He was a man of science.
He shared my passion for the betterment of humanity.
GROVER: Or you could just cut the crap about the betterment of humanity "Kumbaya" stuff since we already know about the yttrium.
STEVE: Okay, here's the facts.
You were conducting secretive and highly illegal mining operations down there.
The night that Jason Kamaka finds out about it, he's killed, and then somebody goes ahead and wipes all the data.
So, unless you can explain to us who else would be trying to cover their tracks Wait, hold on.
Did you say someone just wiped the drives? GROVER: Here's the part where he pretends to be surprised.
- No.
You don't understand.
There's no backup for that data.
Not in my office, not in the cloud, not anywhere.
What? You really expect us to believe that some tech whiz genius forgot to back up his billion-dollar data? It's by design.
The computers on the lab are air-gapped to prevent them from being hacked, which means that no one can access them remotely, including me.
So if someone wiped those drives, it had to be done down at the lab.
Explain something to me.
Why would anybody else erase that drive? Well, there's only one reason: to keep the data away from me and sell it on the open market.
There are foreign interests who would pay hundreds of millions for it.
Oh, well, easy come, easy go.
Looks like you've been had.
I think I know by whom.
- Go on.
- I have an inside man down there, someone I sent for the sole purpose of keeping an eye on the others.
You know, prevent this exact thing from happening.
We're gonna need a name.
All right.
Bleeding stopped.
No sign of infection, but he doesn't look well.
I think the conditions are getting to him.
All right.
Well, I need you to just keep an eye on him, okay? The evac vessel is an hour out.
(exhales) Uh, I'm not feeling so great myself.
Is this that dizziness you warned us about, as our bodies adjust? Yeah.
Yeah.
Yeah, it has to be.
I mean I mean, we just got here.
But Walker, he he should have adjusted a long time ago.
Unless Huh? What are you doing? I saw you check the air when we got here.
You said it was fine.
Yeah, well, not anymore.
Look.
The oxygen levels are dropping to one percent.
Anything below that is dangerously hypoxic.
So someone tampered with the levels after we got here.
Yeah, but why would you mess with the levels if that means that you're affected, too? ADAM: Except, not everyone's affected.
(door opens) TANI: Guys, McGarrett spoke to Nostromo.
There is a third person who knows about the yttrium.
They also have motive to kill Kamaka.
Hey! (shouting) Stay back.
Against the booths, now! Stay back.
Easy, easy.
Okay, Tani, I want you to contact McGarrett and let him know what's going on.
(panting): We can't.
The comms are down.
We're too far from the sub antenna.
We we got to get to the moon pool.
It's barricaded.
We got to break it.
Ready? On three.
One, two, three.
Again.
Two, three.
Oh, she's taking the submersible.
McGarrett? McGarrett, do you read? No.
Without the sub, the comms are gone.
Yeah, along with our only way off this lab.
Sub's gone.
TANI: I'm guessing whatever Kane's exfil plan was after killing Kamaka changed when we got here.
At which point, taking our sub became her best way off the lab.
It looks like she didn't want anyone getting off the lab, period.
Almost all the oxygen supply is gone.
TANI: Joons, exactly how much breathable air do we have left? Well, if we keep all our activity levels down to a minimum, I'm guessing at least 40 minutes to an hour.
Hey, yo! Hey, I just tried calling you.
We got a problem.
What? The GPS on the sub showed movement, right? So Nostromo's people tried to get in touch with them, and-and nothing.
Th-The comms just stopped transmitting.
Did you try to contact them? Several times, got nothing.
GROVER: Well, sound to me like they've been jacked, which means our guys are down there stranded or worse.
Danny, come with me.
Lou, send me the coordinates of the Neptune to my phone, please.
And how far away is that Coast Guard evac vessel? - I'll hit them up and find out.
All right, tell them me and Danny are gonna meet them at the dive site, and, Lou, tell them to hurry.
Yes, sir.
(rapid beeping) Sorry, what are you looking for exactly? Because unless it's a secret cache of oxygen, I don't see the point in exerting yourself.
This is a transmission buoy.
We can put a message on it, and then we send it up to the surface.
It'll broadcast our SOS to all emergency frequencies.
Joons, by the time someone catches that signal and sends a crew down - I know.
It's a Hail Mary, but it's our best shot.
Mayday.
Mayday.
This is Officer Junior Reigns with the Five-O Task Force in urgent need of assistance.
We are six people stranded on board the Neptune One underwater lab.
At 1605, we have roughly 37 minutes left of usable air.
Lab coordinates, north: 21 degrees, 26 tack 927, west: 157 degrees, 62 tack 179.
Depth of 127 meters.
Please contact the Five-O Task Force.
Please send help.
Over.
Wait, Joons.
I'm gonna go.
Let me go.
No.
Look at you.
You can barely stand up.
You don't look too hot yourself.
(beeps) I'll be back.
(inhales) (device beeping) (coughing) (both panting) (grunts) Thanks.
(pained breaths) - I got disoriented.
- Yeah.
(groans) You can get me dinner when we're out of here.
I want sushi.
Okay? Like, really expensive sushi.
Hey.
I went to go to see my dad this morning.
It sucked.
(panting): I'm sorry.
It's okay.
Turns out that's the best part of my day.
Oh.
(coughs) (Tani panting) DANNY: Slow down a little bit.
Slow down.
The GPS says you're right on top of the lab.
- Stop.
- All right.
There's the Coast Guard boat.
That's good.
They should have a diving bell.
I'll go down with the rescue team.
We don't even know what's going on down there.
- They could be dead, for all we know.
- Hey, hey.
Stop.
Please don't do that.
Okay? I'm anxious, too.
We need to stay positive.
So keep your mind on the rescue and not think like that, please.
(beeping) Is that the phone? GROVER: Hey, it's Grover.
Hey, Lou.
What's up? So, a fishing trawler just picked up an SOS message from Junior.
Somehow, the kid got a transmission out.
My man.
Look, it's bad.
He says they're running out of breathable air.
There's six of them down there.
Down to 37 minutes.
Only, the transmission was recorded at 1605.
That's 31 minutes ago.
They got six minutes' worth of air? Which means, by the time that vessel gets here and launches that evac op, it's gonna be too late.
What are you doing now, Beautiful Mind, huh? I'm doing the math.
We got two dive tanks, they're both 80s, which means we've got 160 cubic feet of trimix, right? Which breaks down to approximately 112 minutes of breathable air.
Divide that by the six people that are underneath this, you got a little over 18 minutes each.
If they take turns, they should be able to ration the air in these two tanks and make it last when the Coast Guard gets here with more air.
That's great, but the tanks are up here, so what I imagine is, you're gonna swim those tanks down there? What, you got a better idea? No.
Call the Coast Guard, tell that vessel they need to be here-- they got 18 minutes to get here and get more air down to these people.
Your math is goofy, okay? You got to use some of the air yourself, you got to go down there, you're gonna leave the tanks, come back up, what about you? What about your air, huh? Danny, the best chance of survival for these guys is if I free-dive these tanks down, okay? Now, I got the weight of the tanks.
It's gonna help get me down there.
Ideally, I'd have some kind of guideline, but I don't.
Why don't you use the anchor? There's no way the anchor's gonna reach 130 meters, Danny.
There's no way you're gonna make 130 meters, either.
Let's just be real for a second.
You go down there, you're gonna have to hit a little bit of air, you know? Then what? How are you not gonna explode when you come back up? I'm gonna exhale all of it on the ascent.
But listen, if I get back to this boat and I look like a potato, you got ten minutes to get me to a hyperbaric chamber, all right? Do me a favor, drag this over here.
Come on.
- Steve - Uh-uh.
No pep talks.
Besides, you suck at them.
Thank you.
(deep breathing) (inhales deeply) (deep breathing) (air hissing) Rescue team, 15 minutes.
I can't stay.
Not enough air.
Understand? Make this last.
I got to go.
Stay calm.
One for the road.
(gasping) Steve! You okay? Huh? Everybody else, they okay? Rescue team? Oh.
They'll be there in ten minutes.
It's all good.
Don't ever, ever do that to me again, please.
Now that I know you can hold your breath that long, I don't want to hear you complain when I bring takeout into the car.
Okay? GROVER: Thank you.
- Hey.
- Hey.
Well, I got some very good news on our murderess, Nina Kane.
What's up? Well, the United States Navy tracked her sub, led us right to her dealer.
Wait a minute, we got her in custody? Oh, no.
No, she's in ICU.
In her haste to surface and collect on her payday, she gave herself the bends.
Wow.
Karma really is a bitch sometimes, huh? We got some good news, too.
Uh, Nostromo is gonna do the right thing and, uh, take care of our vic's kid's medical bills.
STEVE: Even the experimental gene therapy treatments.
Kid's covered for life.
That's the least he can do with his rich ass.
STEVE: Well, and assist the Feds in their investigation of his illegal mining operation.
(door opens) Look who's back from the abyss.
STEVE: Hey.
GROVER: Well, look who survived the decompression.
We did, yeah.
16 hours.
16 hours stuck in a hyperbaric-- I'm sorry, scratch that-- hyper-barbaric chamber with, um, Adam and Joons arguing about what's better, cartoons or anime.
- It's anime.
Oh, cartoons.
Come on.
Help me.
Hey, where's Junior? Junior said he would be in later.
He just has to take care of something first.
Okay.
