WE CAN'T DIE
INSIDE COLLAPSING APARTMENT!
This is Detective Kim
from Northern Police Station.
Is your sister Ms. Seo Ju-hee?
Her company reported her missing
after they couldn't reach her
for four days.
When was the last time you talked to her?
We haven't been in touch
since I live in my work dormitory.
I'll check and let you know.
Sure. Please check and get back to me.
I'M BEGGIN YOU, PLEASE BE QUITE.
CANT LIVE LIKE THIS.

The phone you're dialing is turned off.
Please leave a message after a beep.
Just stop it!
I'm not going to let it slide this time.
Seo Ju-hee, stop it.
I said stop!
Didn't you hear it?
They're stomping around now!
It's got to be on purpose!
Yes, it's on purpose.
I'm going to get some evidence this time.
What evidence?
Did you hear that?
You heard that, right?
This apartment is weird!
Stop it!
Seo Ju-hee!
I can't hear anything.
Please stop.
This is our home now.
Adapt and accept it.
Don't cause a scene.
Do you not hear it
or do you refuse to hear it?
She's not home and won't answer my calls.
She's not someone who'd just disappear.
Sure.
Could I talk to someone
who was close to her?
So, even you don't know
where she could be?
No.
What was she like recently?
She asked me if I heard weird sounds
whenever we chatted on the phone.
Weird sounds?
Yes, but I didn't hear anything.
If you remember anything,
here's my contact.
Okay, I will.
Thank you.
Where did she go without her phone?
Who is it?
Could you open the door?
Who are you?
So, you are her sister.
- Do you know my sister?
- Hello. I live downstairs.
Could you be quiet in the evening?
Are you the one
who put the note on my door?
No one's been home for the past few days.
So the noises you heard weren't--
Please do me a favor, okay?
Before I rip your mouth off.

She complained about the noise,
and then disappeared a few days ago?
I haven't seen her in a while either.
And two days ago,
the man downstairs acted
like he'd kill me over the noise.
You really don't know anything?
Your sister
She tore through
the whole apartment building,
saying she had to find
the source of the noise.
I understood her pain,
but it's impossible to locate.
Nobody would say it was them.
Especially because she lives in Unit 604,
everyone's being extra cautious.
What about Unit 604?
What's wrong with my home?
A few months ago
Sir, could you explain
what's going on in the basement?
- Oh, my
- Gosh.
What
I always wondered
where the stench came from.
What's all this?
Illegal dumping that's been piling up
for the past ten years.
I locked the door
so no one could dump there anymore,
but some people still threw garbage
through the window.
They've got no shame.
So you didn't do anything?
No one here has a nose?
Why didn't you file a report
at the district office?
- Well--
- You think we want to let that sit here?
Gosh, Chairwoman.
They refuse to clean private property
with taxpayer money,
and the cleanup is estimated to cost
hundreds of millions of won!
So do we just live
on top of this trash pile?
You have no right to complain.
Who do you think did that?
Would homeowners do this?
It was renters like you!
Because it's not your home.
Excuse me.
I only moved here a week ago,
and I didn't know anything.
Of course, I have the right to complain.
And how are you so sure it was the renters
unless you actually
caught them in the act?
Isn't it obvious?
For goodness' sake.
Who'd want to own a home
in this rundown shithole?
Renting's better.
Gosh!
- Mister!
- Yes?
Lock it up, please.
- Sir?
- Yes?
What we were talking about earlier
What happened in Unit 604?
Well--
- Get a move on.
- Yes.
Here I come, ma'am.
You want to take more days off?
Ju-young, we've been working together
for years.
How could you screw me like this?
Something happened to my sister.
I hired you despite your deafness,
and even got you a dorm because
you didn't want to live with your sister.

Don't you feel bad?
You can't just shove a notice

You know how things are here.

DO I SOUND LIKE A JOKE?
HAPPY BIRTHDAY, JU-YOUNG
HOW TO USE HEARING AID
It's so awkward to record like this.
Anyways, happy birthday.
I was going to write a letter,
but then I heard this new hearing aid
can record
and even play music through Bluetooth.
I know you haven't replaced
your hearing aid in so long,
so I worked hard to save up for you.
I made your favorite dish, japchae, too.
I guess you're home for your birthday.
Ju-young
Don't hate me so much.
By the time you're listening to this,
we'll be face-to-face.
It must be extra awkward.
HAPPY BIRTHDAY!

What's wrong, Ju-hee?
You're
not Ju-hee, right?
A person went missing,
and her sister is unreachable.
- Shouldn't you be worried as her neighbor?
- I'll poke your eyes out!
Can't you be a little more understanding?
Like I said, just get lost
if she doesn't answer,
not bang on the damn door
and bother the whole neighborhood.
If knocking on this door is that noisy,
maybe your ears have a problem.
Whether I knock on the door
or ring the bell, why do you care?
Can you shut your ears?
They're wide open. Look.
Are you about to swing or what?
You were home?
You were home.
What's going on?
He's been knocking around
and causing a ruckus here.
Where the hell have you been?
Are you deaf or something?
Just shut the hell up!
I'm really sorry.
No, not at all.
I'm her sister,
and I didn't know she had a boyfriend.
Well, we haven't been dating that long.
But it has been tough recently.
She stopped answering my calls.
I thought she was ghosting me.
Then she wouldn't answer
her work phone either,
and now you came over.
I'm not sure what's happening with
JU-HEE'S LAST CALLER
Hello?
Why did you ask for a callback?
What are you so curious about?
I'm sorry, but who is this?
She called out of the blue,
and asked about her unit.
What did she ask?
She asked if
The thing is
She asked if a person died there.
It must be that either this young lady
can feel the spirits,
or there really is a ghost.
She'll eventually find out, so I told her.
- A few months ago--
- In my unit?
Yes. A lady who lived in Unit 604
had an unfortunate incident.
She would always complain
that she heard noises.
Then she said
she saw a ghost in the building.
I don't think she was sane.
Then, one day,
we stopped hearing from her.
I thought
I was finally getting some peace.
But then we started to smell a bad stench.
A rotting stench.
No way!
She
hung herself.
Where, in my unit?
Gosh.
I'LL KILL YOU.
I CAN HEAR YOU MOAN, PISS
It has to be the man from Unit 504.
I told him it wasn't my home.
He seems a bit off. Should I talk to him?
No, please don't.
LOOKING FOR MY SISTER
May I use the washroom?
Sure.
Ki-hoon
Please walk softly.
Right, I'm sorry.
Yes, I unlocked her phone.
No, there isn't anything special.
Must a person die before you investigate?
You know that's not what I'm saying.
The man in Unit 504
is acting suspiciously.
He's been posting threatening notes
on my door, knowing that I'm her sister.
He said he'd rip my mouth off.
Did you see him posting them yourself?
We already questioned everyone
and checked the security cameras.
Security cameras?
Then, did you see her leave?
It's an old apartment,
so there's only one at the entrance.
She wasn't in it,
nor on the roadside cameras nearby.
She wasn't captured at all
on the day of her disappearance.
She left her wallet and cell phone too.
There aren't any traces
of her leaving the apartment.
She could have used another exit.
All the more reason to look into Unit 504.
Yeah?
"Did you write threatening notes?"
Should we go and ask him that?
That's not what I meant.
Ju-young, I understand
what you're going through.
But you can't ask for things
that don't make sense.
LOOKING FOR MY SISTER
Thank you for today.
Not at all.
He's the Unit 504 tenant.
I'll talk to him.
What do you want at this hour?
You're being rude.
Two people.
I'll say this for the final time.
Please be quiet at night, I'm begging you.
So? How was he?
- Weird, right?
- Don't even open the door next time.
I think he was hiding something
in his hand.
LOOKING FOR MY SISTER
What are you doing?
Is something there?
Kiddo, are you okay?
What are you doing there?
I'm sorry. I didn't mean to startle you.
- Here.
- Thanks.
If any of my family disappeared,
I'd post flyers too.
But this would upset
the resident association's chairwoman.
There's a rally for a reconstruction
resolution in two days.
What's that got to do
with finding my sister?
Well
Ms. Seo
Would you live in a place
where people died or went missing?
It'd be tough to get approval
for reconstruction with grim rumors.
Even if we get approval
for reconstruction,
if nobody signs the pre-construction deal,
it'll be a bust.
No wonder she doesn't like
what you're doing.
When your sister caused a scene,
looking for the source of the noise,
she even yanked her hair.
Be careful.
If the reconstruction proposal
gets rejected,
someone might end up dying.
Ju-young.
LOOKING FOR MY SISTER
I see you're finally back home.
Ju-hee.
Are you okay? What happened?
Stop it, you're not even
remotely interested in me.
You're wondering why
the girl you hate came back, right?
I actually really missed you,
and I was so scared.

Wait, no!

I've asked you many times.
Please be quiet, okay?
Sons of bitches
Why are you doing this to me?
Who's there?
Who is it?
I can't live like this.
Why would a resident from the fifth floor
jump off the seventh?
You can't go in there.
Ms. Seo?
Are you okay?
Detective, that's the man from Unit 504.
He's the one who has been threatening me.
Ju-hee could be in his unit.
We must search his place.
Are you inside Unit 504?
Did you find anyone inside?
No one, sir.
Copy.
It could be a simple accident.
We can't jump to
any conclusions right now, so
Does that look like an accident?
I understand you're having a hard time,
but you can't make false accusations
based on suspicion.
That's not how this works.
I heard her calling for me
through the sewage pipe.
Look at her, talking crazy.
What did you say?
Hearing voices through pipes?
That doesn't sound crazy to you?
Kidnapping?
Are you trying to screw everyone over?
Why can't you just stay quiet?
Why do you have to get in everyone's way?
You're the ones who are getting in my way.
- What?
- What the
It's not like you'll help.
- Look at this girl talk back.
- She must be crazy.
Maybe Unit 604 is really cursed.
Everyone who lived there was weird.
I know!
The man from before,
and the crazy bitch upstairs.
This girl and her sister.
The man and the crazy bitch?
Who are you talking about?
Did something else happen in that unit?
If you stir up trouble again,
I won't let it slide.
Got that?
Who is it?
Hi, I'm from Unit 604.
Could I speak to you for a moment?
Make yourself at home.
Thank you.
It's my daughter.
Sorry for poking around.
She's adorable.
What did you want to talk about?
The chairwoman--
She lives next door.
You have to be careful.
Everyone can hear each other here.
She mentioned "a man in unit 604"
and "a crazy bitch."
I guess they're previous tenants.
Do you know who they are?
RESIDENT ASSOCIATION
2022 GENERAL ASSEMBLY
The former chairwoman.
She lived in Unit 704 a year ago.
How many times do I have to tell you?
Didn't I tell you to be careful?
If you continue to be noisy,
I'll make sure you can't renew your lease.
I'm sorry.
She was so sensitive to noise,
so I tried to be careful.
But she would still come up frequently
to complain about my child's footsteps.
Be quiet!
You're driving me crazy!
It's not my fault, I was quiet.
I'll shut you up
It's noisy for you too, right?
I told you I won't stay quiet--
Shut up!
Too loud!
Keep quiet, I said!
The man in Unit 604, just below her,
who was also suffering from the noise,
killed her.
- Please be quiet!
- God damn it!
She tapped the wall and floor for help
until she died,
but the residents ignored it,
thinking it was just noise.
All the residents
agreed to keep silent about it
fearing it would affect
the reconstruction approval.
What happened to him?
He disappeared.
No one could find him afterward.
So he's still not caught?
Ju-young, that man from Unit 504
who died today
Why do you think he died?
Some people said they saw that killer man
around the apartment,
while others said
he could've been killed by another tenant.
This place is like
a spider web of grudges.
So, who lives above me in Unit 704?
It's noisy every night, strange noises.
Unit 704 is vacant right now.
Vacant?

I heard there was a murder in Unit 704.
Could you look into it?
SEO JU-YOUNG
Residents of Samil Apartments,
it's truly unfortunate!
With poor materials
and creaking facilities,
we're slowly withering away,
enduring daily noise between floors.
We've done nothing wrong!
Due to this aging
and ailing apartment facility,
Mr. Park Geun-bae from Unit 504
in Building Five has passed away.
This isn't an accident.
It's murder by the city,
ignoring the need for reconstruction!
Everything happening right now
is so tragic and heartbreaking.
At times like this,
we need to stick together even more!
Unite with one goal!
What is she doing?
What's wrong with her?
So, this upsets you
and my missing sister doesn't?
You all know she disappeared!
Are you out of your mind?
This is an important rally!
Do you want to see what crazy looks like?
Screw your reconstruction!
Should I let the world know
how people have been dying here?
Did you really go mad?
You've gone crazy over the reconstruction,
and you don't even care
if people die or go missing!
My sister!
I'm sure that killer took her!
She is somewhere inside this apartment!
I heard her voice!
Ju-young!
- Calm down.
- Let go of me!
What's with you?
Please calm down!
Let go!
Calm down, Ju-young!
One moment, please.
- Let's go.
- Let go
Come on. Let's go.
LOOKING FOR MY SISTER
The killer that you mentioned yesterday
could still be somewhere in the apartment.
I looked into the murder in Unit 704.
They issued a search warrant
and even put out an APB on him,
but still couldn't find him
The security cameras were only installed
in front of the elevator and the entrance.
This is the last time he was captured.
MURDER SUSPECT WANTED
He was never captured on
outside security cameras.
It means he disappeared
within this apartment complex.
No traces of leaving
the apartment complex,
just like Ju-hee.
What if there is a space here
that we haven't searched,
that's tucked away from people
You'll go inside now?
We should inform the police--
You heard our phone conversation.
I told them I was getting death threats,
and even heard her voice
through the pipes,
but they said
there was nothing to investigate.
Look.
No one cares.
I'm the only one
who can find her.
Look, Ju-young.
There's a door here too.
There are two paths.
I think we should split up.
We need to hurry. It'll be night soon.
DAD, LITTLE SISTER, BIG SISTER, MOM
It's your fault.

Shit!

I'll shut you up
Ki-hoon?

What's wrong?
Ju-young!
Hey, there.
Are you alone here?
Can you hear me?
Hey.
Can you hear me?
Congenital hearing loss.
The hearing aid must be uncomfortable.
He takes it off.
Yeon-woo, where did you hide
the hearing aid this time?
Honey, the hearing aid.
Excuse me
What happened?
You were babbling on about
finding someone in the basement.
So I called the police,
and they're searching it.
Get some rest. Your body must be in shock.
What on earth were you doing in there?
- You're lucky I was there to save you.
- Thank you.
By the way
the only kids I've seen here
are your son
and the daughter of the lady in Unit 804.
Did the lady in Unit 804
say she had a daughter?
Yes.
Why do you ask?
Her daughter died on the spot
when a delivery van hit her.
A few years ago.
That lunatic. She's still at it.
Where is it?
Why does he keep taking
the hearing aid off?
It's because you heard something
you shouldn't have.
If you hear it more,
you'll die.
Did you also hear something
in the basement?
I'm looking for someone.
Don't go there.

So, the two of you went to the basement
to look for your sister,
split up and someone started chasing you?
And you don't remember anything afterward?
Yes.
That means someone else was there.
There was a steel door inside,
and another space beyond that.
I need to check that space out--
Ms. Seo, there is no steel door.
We went there and checked every corner.
I'm telling you I saw it.
If I don't go and find Ju-hee--
You saw what happened to Ki-hoon!
Stop causing trouble you can't handle!
You may end up on the suspect list
if you keep this up!
You said you live
in a work dormitory, right?
Why don't you stay there for a few days
It's your fault.

I'm going to record evidence this time.
Is it here?
What is all this?
Don't worry, Ye-na.
No one will hurt you or Mommy now.
Mommy will live here with you forever.

Hide in here.
I'll lure her deeper inside.
You escape through that door.
Open this door!
It's dangerous here. You have to get out.
That woman was still alive, wasn't she?
I heard what you said at home.
I thought I destroyed this.
How did you watch that?
You said she tapped the wall for help.
You saw it with your eyes.
That's how you know.
That woman
kept trying to separate me
from my daughter.
I really had no choice.
I couldn't
let her live.
Are you insane?
Your daughter is dead.
Who said my daughter's dead?
You saw her when you came to my place.

Lock it up, please.
- Sir?
- Yes?
What we were talking about earlier
What happened in Unit 604?
Well--
- Get a move on.
- Yes.
Here I come, ma'am.
You want to take more days off?
Ju-young, we've been working together
for years.
How could you screw me like this?
Something happened to my sister.
I hired you despite your deafness,
and even got you a dorm because
you didn't want to live with your sister.

Don't you feel bad?
You can't just shove a notice
in my face like that.
You know how things are here.
Even one person off the line
can cause a devastating delay.
YOU'RE NOISE IS CAUSIN ME SO MUCH PAIN.
DO I SOUND LIKE A JOKE?
HAPPY BIRTHDAY, JU-YOUNG
HOW TO USE HEARING AID
It's so awkward to record like this.
Anyways, happy birthday.
I was going to write a letter,
but then I heard this new hearing aid
can record
and even play music through Bluetooth.
I know you haven't replaced
your hearing aid in so long,
so I worked hard to save up for you.
I made your favorite dish, japchae, too.
I guess you're home for your birthday.
Ju-young
Don't hate me so much.
By the time you're listening to this,
we'll be face-to-face.
It must be extra awkward.
HAPPY BIRTHDAY!

Shut the fuck up, assholes!
Be quiet or I'll kill you!
Be quiet, for God's sake!
Hear that?
Who is it?
Who's there?
Ju-young, it's me. Open the door, hurry.
Ju-hee?
Ju-young, it's me. Open the door, hurry.
Ju-young, it's me. Open the door, hurry.
Did you forget the passcode?
Ju-hee.
What's wrong, Ju-hee?
You're
not Ju-hee, right?
A person went missing,
and her sister is unreachable.
- Shouldn't you be worried as her neighbor?
- I'll poke your eyes out!
Can't you be a little more understanding?
Like I said, just get lost
if she doesn't answer,
not bang on the damn door
and bother the whole neighborhood.
If knocking on this door is that noisy,
maybe your ears have a problem.
Whether I knock on the door
or ring the bell, why do you care?
Can you shut your ears?
They're wide open. Look.
Are you about to swing or what?
You were home?
You were home.
What's going on?
He's been knocking around
and causing a ruckus here.
Where the hell have you been?
Are you deaf or something?
Just shut the hell up!
I'm really sorry.
No, not at all.
I'm her sister,
and I didn't know she had a boyfriend.
Well, we haven't been dating that long.
But it has been tough recently.
She stopped answering my calls.
I thought she was ghosting me.
Then she wouldn't answer
her work phone either,
and now you came over.
I'm not sure what's happening with
JU-HEE'S LAST CALLER
Hello?
Why did you ask for a callback?
What are you so curious about?
I'm sorry, but who is this?
She called out of the blue,
and asked about her unit.
What did she ask?
She asked if
The thing is
She asked if a person died there.
It must be that either this young lady
can feel the spirits,
or there really is a ghost.
She'll eventually find out, so I told her.
- A few months ago--
- In my unit?
Yes. A lady who lived in Unit 604
had an unfortunate incident.
She would always complain
that she heard noises.
Then she said
she saw a ghost in the building.
I don't think she was sane.
Then, one day,
we stopped hearing from her.
I thought
I was finally getting some peace.
But then we started to smell a bad stench.
A rotting stench.
No way!
She
hung herself.
Where, in my unit?
Gosh.
I'LL KILL YOU.
I CAN HEAR YOU MOAN, PISS
It has to be the man from Unit 504.
I told him it wasn't my home.
He seems a bit off. Should I talk to him?
No, please don't.
LOOKING FOR MY SISTER
May I use the washroom?
Sure.
Ki-hoon
Please walk softly.
Right, I'm sorry.
Yes, I unlocked her phone.
No, there isn't anything special.
Must a person die before you investigate?
You know that's not what I'm saying.
The man in Unit 504
is acting suspiciously.
He's been posting threatening notes
on my door, knowing that I'm her sister.
He said he'd rip my mouth off.
Did you see him posting them yourself?
We already questioned everyone
and checked the security cameras.
Security cameras?
Then, did you see her leave?
It's an old apartment,
so there's only one at the entrance.
She wasn't in it,
nor on the roadside cameras nearby.
She wasn't captured at all
on the day of her disappearance.
She left her wallet and cell phone too.
There aren't any traces
of her leaving the apartment.
She could have used another exit.
All the more reason to look into Unit 504.
Yeah?
"Did you write threatening notes?"
Should we go and ask him that?
That's not what I meant.
Ju-young, I understand
what you're going through.
But you can't ask for things
that don't make sense.
LOOKING FOR MY SISTER
Thank you for today.
Not at all.
He's the Unit 504 tenant.
I'll talk to him.
What do you want at this hour?
You're being rude.
Two people.
I'll say this for the final time.
Please be quiet at night, I'm begging you.
So? How was he?
- Weird, right?
- Don't even open the door next time.
I think he was hiding something
in his hand.
LOOKING FOR MY SISTER
What are you doing?
Is something there?
Kiddo, are you okay?
What are you doing there?
I'm sorry. I didn't mean to startle you.
- Here.
- Thanks.
If any of my family disappeared,
I'd post flyers too.
But this would upset
the resident association's chairwoman.
There's a rally for a reconstruction
resolution in two days.
What's that got to do
with finding my sister?
Well
Ms. Seo
Would you live in a place
where people died or went missing?
It'd be tough to get approval
for reconstruction with grim rumors.
Even if we get approval
for reconstruction,
if nobody signs the pre-construction deal,
it'll be a bust.
No wonder she doesn't like
what you're doing.
When your sister caused a scene,
looking for the source of the noise,
she even yanked her hair.
Be careful.
If the reconstruction proposal
gets rejected,
someone might end up dying.
Ju-young.
LOOKING FOR MY SISTER
I see you're finally back home.
Ju-hee.
Are you okay? What happened?
Stop it, you're not even
remotely interested in me.
You're wondering why
the girl you hate came back, right?
I actually really missed you,
and I was so scared.
Ju-hee
Ju-hee!
Wait, no!

Please be quiet.
I've asked you many times.
Please be quiet, okay?
Sons of bitches
Why are you doing this to me?
Who's there?
Who is it?
I can't live like this.
Why would a resident from the fifth floor
jump off the seventh?
You can't go in there.
Ms. Seo?
Are you okay?
Detective, that's the man from Unit 504.
He's the one who has been threatening me.
Ju-hee could be in his unit.
We must search his place.
Are you inside Unit 504?
Did you find anyone inside?
No one, sir.
Copy.
It could be a simple accident.
We can't jump to
any conclusions right now, so
Does that look like an accident?
I understand you're having a hard time,
but you can't make false accusations
based on suspicion.
That's not how this works.
I heard her calling for me
through the sewage pipe.
Look at her, talking crazy.
What did you say?
Hearing voices through pipes?
That doesn't sound crazy to you?
Kidnapping?
Are you trying to screw everyone over?
Why can't you just stay quiet?
Why do you have to get in everyone's way?
You're the ones who are getting in my way.
- What?
- What the
It's not like you'll help.
- Look at this girl talk back.
- She must be crazy.
Maybe Unit 604 is really cursed.
Everyone who lived there was weird.
I know!
The man from before,
and the crazy bitch upstairs.
This girl and her sister.
The man and the crazy bitch?
Who are you talking about?
Did something else happen in that unit?
If you stir up trouble again,
I won't let it slide.
Got that?
Who is it?
Hi, I'm from Unit 604.
Could I speak to you for a moment?
Make yourself at home.
Thank you.
It's my daughter.
Sorry for poking around.
She's adorable.
What did you want to talk about?
The chairwoman--
She lives next door.
You have to be careful.
Everyone can hear each other here.
She mentioned "a man in unit 604"
and "a crazy bitch."
I guess they're previous tenants.
Do you know who they are?
RESIDENT ASSOCIATION
2022 GENERAL ASSEMBLY
The former chairwoman.
She lived in Unit 704 a year ago.
How many times do I have to tell you?
Didn't I tell you to be careful?
If you continue to be noisy,
I'll make sure you can't renew your lease.
I'm sorry.
She was so sensitive to noise,
so I tried to be careful.
But she would still come up frequently
to complain about my child's footsteps.
Be quiet!
You're driving me crazy!
It's not my fault, I was quiet.
I'll shut you up
It's noisy for you too, right?
I told you I won't stay quiet--
Shut up!
Too loud!
Keep quiet, I said!
The man in Unit 604, just below her,
who was also suffering from the noise,
killed her.
- Please be quiet!
- God damn it!
She tapped the wall and floor for help
until she died,
but the residents ignored it,
thinking it was just noise.
All the residents
agreed to keep silent about it
fearing it would affect
the reconstruction approval.
What happened to him?
He disappeared.
No one could find him afterward.
So he's still not caught?
Ju-young, that man from Unit 504
who died today
Why do you think he died?
Some people said they saw that killer man
around the apartment,
while others said
he could've been killed by another tenant.
This place is like
a spider web of grudges.
So, who lives above me in Unit 704?
It's noisy every night, strange noises.
Unit 704 is vacant right now.
Vacant?
Ki-hoon
I heard there was a murder in Unit 704.
Could you look into it?
SEO JU-YOUNG
Residents of Samil Apartments,
it's truly unfortunate!
With poor materials
and creaking facilities,
we're slowly withering away,
enduring daily noise between floors.
We've done nothing wrong!
Due to this aging
and ailing apartment facility,
Mr. Park Geun-bae from Unit 504
in Building Five has passed away.
This isn't an accident.
It's murder by the city,
ignoring the need for reconstruction!
Everything happening right now
is so tragic and heartbreaking.
At times like this,
we need to stick together even more!
Unite with one goal!
What is she doing?
What's wrong with her?
So, this upsets you
and my missing sister doesn't?
You all know she disappeared!
Are you out of your mind?
This is an important rally!
Do you want to see what crazy looks like?
Screw your reconstruction!
Should I let the world know
how people have been dying here?
Did you really go mad?
You've gone crazy over the reconstruction,
and you don't even care
if people die or go missing!
My sister!
I'm sure that killer took her!
She is somewhere inside this apartment!
I heard her voice!
Ju-young!
- Calm down.
- Let go of me!
What's with you?
Please calm down!
Let go!
Calm down, Ju-young!
One moment, please.
- Let's go.
- Let go
Come on. Let's go.
LOOKING FOR MY SISTER
The killer that you mentioned yesterday
could still be somewhere in the apartment.
I looked into the murder in Unit 704.
They issued a search warrant
and even put out an APB on him,
but still couldn't find him
The security cameras were only installed
in front of the elevator and the entrance.
This is the last time he was captured.
MURDER SUSPECT WANTED
He was never captured on
outside security cameras.
It means he disappeared
within this apartment complex.
No traces of leaving
the apartment complex,
just like Ju-hee.
What if there is a space here
that we haven't searched,
that's tucked away from people
You'll go inside now?
We should inform the police--
You heard our phone conversation.
I told them I was getting death threats,
and even heard her voice
through the pipes,
but they said
there was nothing to investigate.
Look.
No one cares.
I'm the only one
who can find her.
Look, Ju-young.
There's a door here too.
There are two paths.
I think we should split up.
We need to hurry. It'll be night soon.
DAD, LITTLE SISTER, BIG SISTER, MOM
It's your fault.
Where am I
Shit!
MURDER SUSPECT WANTED
Ki-hoon?
Ki-hoon?
I think there's more space over here.
I think we should take a look inside.
Everyone's noisy, except me.
Ki-hoon, what are you doing?
It's not my fault. I was quiet.
I'll shut you up
Ki-hoon?
Ki-hoon!
What's wrong?
Ju-young!
Hey, there.
Are you alone here?
Can you hear me?
Hey.
Can you hear me?
Congenital hearing loss.
The hearing aid must be uncomfortable.
He takes it off.
Yeon-woo, where did you hide
the hearing aid this time?
Honey, the hearing aid.
Excuse me
What happened?
You were babbling on about
finding someone in the basement.
So I called the police,
and they're searching it.
Get some rest. Your body must be in shock.
What on earth were you doing in there?
- You're lucky I was there to save you.
- Thank you.
By the way
the only kids I've seen here
are your son
and the daughter of the lady in Unit 804.
Did the lady in Unit 804
say she had a daughter?
Yes.
Why do you ask?
Her daughter died on the spot
when a delivery van hit her.
A few years ago.
That lunatic. She's still at it.
Where is it?
Why does he keep taking
the hearing aid off?
It's because you heard something
you shouldn't have.
If you hear it more,
you'll die.
Did you also hear something
in the basement?
I'm looking for someone.
Don't go there.
DETECTIVE KIM
Ki-hoon. Let me through
- Ki-hoon
- You can't go in there!
Let me through!
This camcorder can save files
to a phone via Wi-Fi or Bluetooth.
Though the camcorder was damaged,
the phone was unlocked,
so we could check the saved videos,
despite some corrupted footage.
Ms. Seo
So, the two of you went to the basement
to look for your sister,
split up and someone started chasing you?
And you don't remember anything afterward?
Yes.
That means someone else was there.
There was a steel door inside,
and another space beyond that.
I need to check that space out--
Ms. Seo, there is no steel door.
We went there and checked every corner.
I'm telling you I saw it.
If I don't go and find Ju-hee--
You saw what happened to Ki-hoon!
Stop causing trouble you can't handle!
You may end up on the suspect list
if you keep this up!
You said you live
in a work dormitory, right?
Why don't you stay there for a few days
It's your fault.
Where is it?
I'm going to record evidence this time.
Is it here?
What is all this?
Don't worry, Ye-na.
No one will hurt you or Mommy now.
Mommy will live here with you forever.
What is it?
The lady next door keeps bothering you?
It's okay.
I can kill her like the lady downstairs.
Did you hear what I said?
What were you doing alone?
You did more than just listen.
Ju-young.
Ju-hee.
Ju-hee?
Ju-hee.
Ju-hee.
Ju-hee.
Ju-hee, please.
Are you okay?
It's okay. Everything's okay.
Let's get out of here.
Let's go.
Found you.
Ju-young?
Ju-young.
Open this door.
Hide in here.
I'll lure her deeper inside.
You escape through that door.
Open this door!
It's dangerous here. You have to get out.
That woman was still alive, wasn't she?
I heard what you said at home.
I thought I destroyed this.
How did you watch that?
You said she tapped the wall for help.
You saw it with your eyes.
That's how you know.
That woman
kept trying to separate me
from my daughter.
I really had no choice.
I couldn't
let her live.
Are you insane?
Your daughter is dead.
Who said my daughter's dead?
You saw her when you came to my place.
You're just like me.
SPEECH RECOGNITION MODE
HAHAHAHAHAHAHA
HAHAHAHAHAHAHA
Because of people complaining
about Ye-na running at home,
I let Ye-na play outside.
I should have protected her.
She went outside and
She was run over by that huge truck.
It's all your fault.
She died because of the noise made
by all of you!
Why?
What did I do wrong?
Why did that bitch
and your sister mess with us?
Crazy bastards
I'm sorry!
I didn't want to kill them!
What are you saying?
My sister is alive.
What's with you?
Help me, please!
Help!
Help!
Please help!
Help!
Ju-hee.
Ju-hee?
Ju-hee.
Don't listen.
It's nothing. It's okay.
Don't listen.
Please
Help

Good afternoon.
I moved into the unit above you
a few days ago.
Hello.
Do you live alone?
With my sister.
Right. I brought this for you.
I'LL BE A GOOD NEIGHBOR
I'll try to be as quiet as possible,
but if you hear any noise,
feel free to let me know.
The unit above me
was really noisy at night.
I don't know how people can be so noisy
day and night--
You have to be careful.
Everyone can hear each other here.
