Gap Dong (갑동이)

Whose is it?

Dr. Han's?

Badge no. 83-5045 wasn't...

...for Dr. Han…

No?

- Then who? - Well.

In 1983...

…Mr. Yang received it.

You sure? The badge is…

…Mr. Yang's?

I checked many times.

What is the badge anyway?

[Iltan Police Station Yang Chul Gon]

I was Gap Dong.

You were Gap Dong?

Yes. Me too.

I was Gap Dong too.

That makes no sense.

How can Gap Dong look for Gap Dong?

What do you mean?

You committed all 9 crimes?

When I said...

...there could be 2 or 3 Gap Dongs...

…I was talking about myself.

What is it, honey?

Nothing much. Scary Tiger's at it again.

Is Mr. Yang suspecting you?

I said no.

Looking for this?

A badge is like a cop's name tag.

There was blood on Mr. Yang's badge...

...and you hid it for him.

Shouldn't you explain this?

I thought it was a trap.

A trap?

Today at 2AM...

...I was on stakeout...

...to catch Gap Dong despite my suspension.

Gyeonggi Police are hiring 15,000 more people...

...to solve the Iltan serial murder case.

Those who report suspects...

...will now receive $50,000 instead of $20,000.

On the dark rainy night...

...I chased after the person dressed in a man's raincoat.

Thinking I was Gap Dong...

...the victim fell below a river bank trying to run away.

Unfortunately when I had reached her...

...she had stopped breathing.

I don't think my mistake can...

...ever be forgiven.

Premeditated or not...

...I am prepared to accept any kind of punishment.

May 26, 1995.

Yang Chul Gon.

Known as a copycat...

...Ryu Tae Oh left for Zurich at 21:00.

The day after tomorrow is the forewarned 7th crime day…

…so hopefully the 7th case will not occur.

But I'll explain...

...about the case just in case.

May 26, 1995 around 2AM.

Due to sudden rain…

…Han went out to tend to her pepper plants.

She was killed below the river bank.

The crucial items are her rainboots, raincoat...

...and electric wire.

Fishing knot and muzzle.

I thought it was another Gap Dong case.

Then…

But it was Yang's who was suspended then.

No. 83-5045.

I saw his reinstatement petition.

So you hid it on purpose?

I wanted to hide it for him…

…and I had to.

The victim had...

...the badge.

As if for show.

As if to target Yang.

Target?

If someone were to catch Gap Dong...

...it would be Yang.

Why didn't you reveal everything then?

Even the president was...

...pressuring us to find Gap Dong.

If hard evidence came up...

...you couldn't avoid the accusation.

Back then…

…it would have been the death penalty.

I'm still wondering…

…if I made the right decision.

The crime method was identical.

Excuse me.

I did some research and found the 7th case unique.

The decisive reason for death was from a fall...

...not strangulation.

I don't know if that matters much now.

Yeah, it's not like the 7th case will happen.

Yes.

You should come arrest me.

So...

...you both mistook each other for Gap Dong.

Yeah, so she ended up dying from the fall.

I heard from Mr. Han.

He firmly believes it was a trap.

Gosh.

I never treated him well…

But what's with the badge?

Why was it in the victim's hand?

Police…

Police…

I killed her trying to catch Gap Dong.

The moment she stopped breathing…

- …I was out of my mind. - You should've confessed right away.

But I couldn't bring myself to do it.

I drank alcohol to pluck up the courage.

But I realized it wasn't necessary.

What do you mean?

I had left...

...my badge at the scene.

I don’t understand.

You're saying...

...she died due to a misunderstanding-related accident.

But Gap Dong's signature was there.

It wasn't just a falling accident.

Yeah.

That's what makes me go crazy.

When I went to submit this confession statement...

...that case had already...

…become the 7th case.

Then Gap Dong had been watching you in the accident?

Yes.

When I was waiting in ambash to catch him…

…Gap Dong was watching me.

Having fun…

Gap Dong...

After I left the scene...

...he held a ritual over the dead body…

…for himself.

Then Gap Dong had been watching you in the accident?

Yes.

When I was waiting in ambash to catch him…

…Gap Dong was watching me.

Having fun…

Gap Dong...

After I left the scene...

...he held a ritual over the dead body…

…for himself.

The 7th case fishing knot...

...was a ritual, not a signature.

Why didn't you submit this statement?

It's raggedy. You must've carried it with you always.

The moment I catch Gap Dong…

…I wanted to pay for my mistake then.

So stubborn…

What are you concerned about?

Go tell Mr. Cha now.

If you don’t want...

...a spot on your detective record.

Ha Mu Yeom.

Don’t let it happen to you too.

If things get entangled trying to catch Gap Dong...

…your life will get entangled too.

You want some boiled chicken?

Weren't you two enemies?

Nah.

Geez.

This was what you wanted to know so badly.

The blood on my father's jacket.

I loved this boiled chicken.

Since I kept nagging him when we were poor...

...he stole someone's chicken.

But as you know…

…since he's a bit slow…

…he couldn’t tell me…

…that he'd actually stolen the chicken.

The blood on the jacket…

…was chicken blood.

Since he stole the chicken after all and stealing…

…is bad.

You were right.

I suspected my father.

That's why I burned it...

...not knowing it was chicken's blood.

I made my father's innocence...

...unprovable…

…for good.

That was it?

The big secret…

We're in the same boat.

We live in guilt...

...because of Gap Dong.

If it weren't for that guilt…

…I could've given up...

...on catching him long ago.

Whose is it?

Dr. Han's?

Her real name is Kim Jae Hee.

Witness to the old 9th case.

Oh, my son in law...
