Signal (시그널)

Lieutenant Park, this is Lee Jae-han.

Who are you? Seonil Mental Hospital?

What's with you? How did you know it was Seo Hyung-joon?

-Are you crazy? -It's our only chance to find him.

Jae-han? Thanks to you, we solved the case.

Did you hear the news? Which branch are you in?

This might be my last transmission.

A cold case squad will be officially set up in Seoul.

This was his first case, right?

The South Gyeonggi serial murders. Our most famous unsolved case.

-So he did move already. -It's worth a try.

It's unbelievable.

Let's talk instead.

Jae-han?

This is Lee Jae-han from Yeongsan Branch.

Ohsung mountain?

The victim was found next to the acacia trees near route three, right?

Who the hell are you?

I'm looking for Lieutenant Park Hae-young.

-I heard something weird. -Get out!

Did I hear it wrong?

ATTEMPTED MURDER

That walkie-talkie was real.

EPISODE 3

LEE MI-SEON ATTEMPTED MURDER

Where is it?

HYUNPOONG STATION RAILROAD

Did you do that?

What do you mean?

The victim Lee Mi-seon listed as a survivor.

That's correct.

She is a survivor.

ATTEMPTED MURDER

What's up?

It's about Lee Mi-seon, who was killed at Hyunpoong Station.

What are you talking about?

That was an attempted murder.

What do you mean? An attempted murder?

She definitely died.

Profiler Park, can't you read?

Lee Mi-seon survived for sure.

I'll untie you.

Just hold on. I'll untie you.

It's okay. I'm a police officer.

-What? -You bastard!

Wait!

Why are you doing this to me?

You punk.

Can I help you?

Hello.

I'm Lieutenant Park Hae-young from Seoul Metropolitan Police.

You're Kim Chang-soo, in charge of the South Gyeonggi serial murders, right?

-Please, I just have to ask one thing. -Go away! I have nothing to say.

The Hyunpoong Station.

Did Lee Mi-seon really survive there?

What exactly happened?

It's all that bastard of a cop's fault.

Lee Jae-han from Yeongsan Branch.

Lee Jae-han?

He was babbling about

receiving a weird radio message.

Radio message...

He ruined

everything.

It's all his fault!

Hello.

Get out quick!

Gosh, I can't believe this.

Seriously.

-Is it him? -Yes, I caught him on the scene.

I have a witness who he tried to kill.

Detective, I didn't do anything.

-Be quiet. -Take him inside.

I didn't do anything wrong.

I'm innocent!

This is crazy. Let go of me!

Let go! I didn't do it!

-Good job. -Thank you!

Good job.

LEE MI-SEON ATTEMPTED MURDER

This is Jae-han. Hae-young, are you there?

It's Seo Hyung-joon's corpse, the suspect of the case.

Seo Hyung-joon died in 2000.

But he said "corpse,"

instead of "skeleton."

This might be

my last transmission.

The last transmission

in 2000.

But this is not the end.

The message will start again.

When it does,

you should persuade me.

Persuade me back in 1989.

Constable Lee Jae-han

living in 1989.

This is constable Lee Jae-han of Yeongsan Branch. Who is this?

Is there a cop in this country who doesn't know that?

The seventh was

in a reed field near route three.

The eighth was on the railroad at Hyunpoong Station.

It's all that bastard of a cop's fault.

Lee Jae-han from Yeongsan Branch.

I heard that the eighth murder will happen at Hyunpoong Station.

Get out!

He was babbling about

receiving radio messages.

This makes no sense.

This is impossible.

This is constable Lee Jae-han of Yeongsan Branch.

This is constable Lee Jae-han of Yeongsan Branch. Who is this?

Who the hell are you?

Lieutenant Park?

This is Lee Jae-han.

Who are you, seriously?

What have you done to me?

I don't know what you're saying,

but I caught the killer on Hyunpoong railroad.

This is all because of your help.

But...

I'm really curious.

How did you know about the Hyunpoong railroad?

Are you...

trying to joke around with me?

Where are you?

I'll come over right now.

Where are you?

Where do you think? I'm at Ohsung Police Station.

I handed over Choi Young-shin.

SUSPECT ARRESTED CHOI YOUNG-SHIN

You really...

arrested

Choi Young-shin?

Yes, I did.

He was a young, unemployed loser.

Are you really

saying...

that it's 1989 over there?

Why do you keep asking? Are you okay?

I don't know

why you're trying to fool me.

But...

if it's really 1989 over there,

Choi Young-shin is going to die!

You're driving me crazy!

Is this how detectives treat people?

-Get up! -Wait a minute.

Keep walking, you punk!

Detective, hold on a bit.

Wait.

What do you mean?

Why would he die?

He's not the culprit!

At the time of death,

the eighth victim will die in front of Ohsung Daesung Supermarket.

If you are really living in 1989,

you should be able to stop it.

What the hell do you mean?

Hae-young?

Hello?

Walk properly.

Stand up, you jerk.

-Wait a second. -Stop acting!

DIED DUE TO SEIZURE

EIGHTH VICTIM OHSUNG DAESUNG SUPERMARKET

IN FRONT OF OHSUNG DAESUNG SUPERMARKET

No, it can't happen.

What happened?

What? Why?

-Hey! -Wake up!

Min-joo...

Another victim has been found! In front of Ohsung Daesung Supermarket!

She's the eighth victim.

Choi Young-shin is not the culprit!

At the time of his death,

the eighth victim will die in front of the Ohsung Daesung Supermarket.

IN FRONT OF OHSUNG DAESUNG SUPERMARKET

THE EIGHTH VICTIM HWANG MIN-JOO

WRONGFULLY ACCUSED MAN DIES IN CUSTODY

The articles have changed as well.

LEE JAE-HAN YEONGSAN POLICE STATION

How could this be?

The transmissions...

They were real.

A CONSTABLE SAVES WOMAN LEE JAE-HAN

I just need a few minutes.

Go away!

We're re-investigating

the South Gyeonggi case.

Your wife was

the sole survivor.

She told everything to the cops!

It was so dark that she doesn't remember anything.

I'm sorry,

but any belongings--

Like you said, she survived

even after that terrible attack.

But...

do you know who killed her in the end?

It's people like you.
