The tour of duty lasts forthree months during which nobody is allowed to leave.

Put it down now!

Don't move and put it down!

Don't fucking shoot!

The Guard Post

The funeral is tomorrow?

Yes.

He's all grown up.

- Which guard post is it? - 506

- lsn't that... - Yes...

It's headed by the army chief's son.

That's why you came to me.

Nobody wants blood on their hands.

It's the Commander-in-Chief.

Just be careful. It could cost you your job.

Nobody wants this to get out.

Everybody was killed except the one in a coma.

He's the only suspect.

That's all we know so far.

You only have tonight.

Tomorrow, they'll try to cover it up so they won't get burnt.

Get to the truth before that happens.

Remember. You only have tonight.

- We're looking for him. - He's a platoon leader.

Look for his dog tags. Just find him as soon as possible.

But Doc says we're damaging the bodies.

Are you kidding me?

Forget it.

Just send the bodies over.

But ClD radioed us to keep the scene intact.

Listen, asshole! Everyone's going nuts here!

- This is your commander speaking. - Yes, Sir!

Send over the bodies and the survivor now, understood?

Yes, Sir!

Fuck me!

Kill them all

On the double!

Collect the bodies first.

And put the body parts in a separate bag.

Hey, you missed one here.

What's going on?

They were yelling my ears off.

- We called you, didn't we? - You know how it works.

Move it, boys.

- We've been expecting you. - OK.

I'm First Lieutenant Bang.

I heard there was a survivor. Where's your doctor?

Follow me.

The guys from ClD are here.

Hello. Sergeant Major Noh of ClD reporting.

How is he?

Not sure. I'm just surprised to see him still alive.

He didn't have a tag.

So we haven't identified him yet.

Any other survivors?

He's the only one.

And the only suspect.

Not done yet? Hurry up and let's hit the road.

We need to move the survivor.

Where are you going?

Why don't you ask Bang?

As I told you, HQ is being really pushy...

- Bang. - Yes?

As of this moment, l have full operational control over all personnel.

You're not going anywhere unless l authorize it.

What if they make us stay here?

Don't jinx it.

Killing them wasn't enough?

Why pour kerosene all over them?

Nothing significant here.

A cake?

They had a party here?

Aren't those dog tags?

Jin-won Kang

I've found you, Corporal Kang.

Why did he do this?

Crazy son of a bitch.

Why kill all these people?

Sir?

I think they closed this section.

It's like a maze in here.

Corporal Kang must be a psycho.

He wasn't disciplined properly.

Too much slack is never...

Stop!

Stop!

The body count isn't correct?

All l know is we have 19 bodies with us.

If so...

Dead or alive, we're missing one.

21 were stationed here.

- lt's not our mess-up. - Please, check again.

- ln this rain? - Yes.

It'll damage the bodies.

Doesn't matter.

Look, Mr lnvestigator, I'm done here.

Treating him is the only...

- You heard him. - Yes, Sir.

Hey, unload the bodies!

Ready? One, two, three...

Hey, not too rough.

It's 19!

Can we leave now?

Yes.

Bang?

I'll have the boys search again.

Nothing here!

It's clean.

- What's wrong with them? - What the fuck is up with them today?

What are you scared of?

Chunja's barking like hell tonight.

Is she in heat?

That crazy mutt...

She must be in heat.

Hey.

Yes, Private Cho!

Go shut that mutt up.

Yes, Sir!

What's wrong with you tonight?

Why so much racket?

Be quiet so we can sleep.

I said quiet!

Chunja?

Chunja?

What's wrong?

Chunja?

Chunja?

What's wrong?

Sergeant Ma?

Sergeant Ma?

What's wrong? Are you OK?

Like I needed this!

That fucking mutt!

Get those dogs!

Get them!

Not bad having an army chief for a dad, is it?

There are two groups of bodies.

Those found in the boiler room were dead at least two days. A day for the others.

Do you think he got into the armoury?

It seems that somebody was controlling the weapons.

All the personal weapons were found in the armoury,

not in the barracks.

It's weird, though.

These old bunkers are usually crowded with rats.

But l haven't seen one here with all the bodies lying around.

What is it?

Come any closer...

and l'll kill you!

Get away!

Go!

Get back!

Get away from me!

It's OK. Don't be afraid.

Get back!

You're safe now.

Fuck you. Get back!

It's OK now.

Fuck you!

Slow down and talk to me.

What's your name?

Your name!

You son of a...

What the...

I'm First Lieutenant Yoo head of Guard Post 506.

So you're...

Can l get a cigarette?

Excuse us for a minute.

What are you doing? We have work to do!

Let's go.

I understand what you're going through.

- But you need to cooperate... - Only after I get back to the main force.

Listen, Yoo. This won't do you any good.

A soldier talks in a soldier's way.

Like a soldier!

Remember, Noh.

You're a soldier, not a cop.

Get me back to the base.

Take him to the base.

The interrogation's still...

Interrogation my ass! Send him over right away!

This is my case.

Save it and do as I say!

I'm in charge of this case until 6am.

What? You must be crazy.
