The Guest (손: The Guest)

I heard he was going somewhere.

Tell me where he went.

Where is he going all the time when we're busy?

Is he ditching work again?

Call Detective Kang.

Yes, sir.

The line is currently busy...

She's not answering.

Call Detective Goh then.

No, forget it. I'll do it.

Hello? Where are you?

Didn't you say you were going home?

I'm sorry, Bong Sang. I'm at Gyeyangjin.

What on earth are you doing over there right now?

What kind of detective is on the phone all day?

Who is he talking on the phone with?

Something urgent came up. Let's talk later.

Gil Young, wait. Hello?

Hey!

Yes, Boss. - Where are you?

I'm here to catch Gu Byeong Gil.

You know, that theft case in Yangja-dong.

What about Detective Kang? Is she with you?

Yes, she's with me. But Gil Young is currently...

Do you know Octopus, the friend of Gu Byeong Gil?

We caught him right now.

Hold on.

Gil Young, the boss is on the phone.

Hey, what's wrong?

What are you doing?

Gil Young, don't do that. This is your last chance.

Sir, I have to stop Gil Young right now.

I'll call you back. - Stop her.

Gil Young, you brat.

I'm sorry about the phone call. - It's fine.

Anyway, I'm glad to hear you are doing well.

So what brings you all the way to Gyeyangjin?

I have something to ask about the Song Hyeon Ju case.

What about...

that case?

You know...

that it was the last case Mom was in charge of.

Yes, it was.

How's the investigation going?

We just found her body.

We'll have to start investigating now.

But it's already been 20 years.

The statute of limitations has expired.

Even if it has expired,

we have to catch the killer.

We have a suspect.

I saw it on Mom's note.

That's ridiculous.

Why?

Because she is famous now?

That was merely your mom's groundless claim.

Then why is a congresswoman...

No,

why is Park Hong Joo, the daughter of...

Gyeyangjin High School's director a suspect?

You were team members with Mom back then, and you probably know.

On that night at the school,

a guard testified that he saw Park Hong Joo...

and Song Hyeon Ju talking.

But he changed his testimony shortly after,

saying he got confused with the date.

On the day she went missing, Congresswoman Park Hong Joo...

was with her family.

Park Hong Joo was the daughter of the director of that high school.

You know well enough.

Witnesses change their testimonies all the time...

and they're not even indicted.

Eventually, the whole thing gets covered up.

We must re-investigate.

Where is that guard?

Gil Young.

Your mom was amazing.

She was a talented detective.

She was kind to me when I was a rookie,

and she deserved to be respected.

I still can't...

forget that day.

I'm at the private villa at the intersection of Yunmyeon 2-ri.

Bring all the backup you can.

The person who received her last call for backup...

was me.

It still feels like...

there is a knot inside my heart.

In my 20 years as a police officer,

I regret that moment the most and it hurts me.

I feel the same as you.

I want to solve your mother's last case.

However, for this case, your mom made a mistake.

She claimed it was a murder without any evidence.

But she was right.

The girl wasn't just a runaway. She was murdered.

I'm talking about suspecting Park Hong Joo.

I still don't understand why your mom had that absurd idea.

Gil Young, this is what I told your mom as well.

If we mess with someone like Park Hong Joo,

people like us will end up losing our jobs.

You know that too.

Park Hong Joo?

You mean that local Congresswoman?

Yes. It seems like...

she had been living in Gyeyangjin until 20 years ago.

Gyeyangjin High School was owned by her family.

She was the director of the foundation.

Hold on.

When your brother's case happened,

she must have been living in that area.

Yes.

Around that time, she resigned as director.

What about the recent possession cases in Sangyong City?

They happened around the time...

when she won the by-election in Sangyong City.

Are you thinking what I'm thinking?

It's a possibility.

So far, she is the only person...

who has been in contact with the possessed people.

All right. Let me call you back.

Detective Kang.

How did it go? Is there any suspect in the Song Hyeon Ju case?

Why do you want to know?

Her body was found right next to Priest Choi's remains.

It must have something to do with Park Il Do.

We don't know about that yet.

It might be a simple murder.

Seriously.

You said we should catch Park Il Do together.

I just heard something incredible.

Have you heard of Park Hong Joo?

Park Hong Joo?

I just talked to Priest Mateo on the phone.

The possessed people are related to Park Hong Joo...

through Sharing Hands.

That can't be just a coincidence.

The suspect in the high school girl case is...

Park Hong Joo.

Why did you skip the Bible study and went to an internet cafe?

Just because. It's boring.

He's over there.

Do you know what happens if you skip Bible study...

and lie?

You'll receive serious punishment.

Like what?

You'll go to the fiery pit.

The biggest Satan there...

will make sure you can't play any more games.

The Satan is super powerful.

You sound like an old man.

An old man?

You're so boring.

Right back at you!

You little brats.

I'll tell the priest to punish you guys.

Whatever.

Where are you going? You little...

You saw everything?

You haven't changed a bit.

You still tell silly jokes to kids who skip services.

You did that to me too.

Your brother was the only one who played along with my jokes.

What brings you here today?

You want more information on Sharing Hands?

No. I'd like to ask you something.

Last time we were in Gyeyangjin together,

we saw that lady,

Congresswoman Park Hong Joo.

Congresswoman Park?

I told you about her.

She's been helping Sharing Hands, and I owe her a lot.

Haven't you noticed anything strange about her?

Strange?

It seems like...

she is related to the people possessed by Park Il Do.

Kim Young Soo, Choi Min Sang, and Kim Yoon Hee.

All of them.

Are you saying Congresswoman Park is Park Il Do?

Do you seriously believe that?

Isn't that just absurd?

What makes you think so?

The reason why she met the three of them is...

because she's been active in Sharing Hands.

It's nothing strange.

Most of all,

she is a devout believer.

She comes here all the time.

She comes to the church?

In addition to her relation to Sharing Hands,

she even killed the high school girl?

She's more and more suspicious.

We don't know if she's the killer yet.

Okay.

Where are you going? Wait in the car.

Why don't you wait in the car?

This is not your jurisdiction. Are you allowed to poke around here?

You're reporters?

I kept saying she wasn't just a runaway,

but no one believed me.
