Undercover High School (언더커버 하이스쿨)

Let me...

Let me first call the cops.

Don't.

These aren't human remains. It's plastic.

Who's there?

I was wondering why the door was open.

What are students doing in here?

Principal Park.

It's a skeleton model.

We came to see if the ghost story was true...

and stumbled upon it.

- What ghost story? - They say this place is haunted.

The ballet studio, to be exact.

Who would do such a thing?

Actually, when we got here...

We don't know.

I apologize for trespassing.

It won't happen again.

You'd better behave yourselves.

Yes, sir.

Why did you stop me from telling him?

About that person who was here before us.

We don't know for sure who it was.

I thought telling him would only make things worse.

Who do you think it was?

Time will tell.

Byeongmun High's school uniform from the 1950s,

the ballet studio,

a skeleton model missing legs, and a tutu.

The scene was staged...

to perfectly fit the ghost story of the old building.

Why though?

And who?

This is a key I found next to the skeleton.

Look at the seal on it.

It's a perfect match with Seo Byeong Mun's.

What we should especially focus on is the phrase on its side.

It translates to "The beginning of the gold bar."

The character itself doesn't mean "bar" though.

Doesn't that mean odd or bizarre?

It's used to make up the word for "ghost story."

Are you saying...

there's a connection between the ghost story and the gold bars?

As of now, yes.

The ghost story itself is the key to finding the gold bars?

Seo Byeong Mun who hid the gold bars...

set up the ghost story as a riddle.

One must solve the ghost story...

to gain access to the gold bars.

As of now, there are more questions than answers.

However, I'm certain of two things.

A...

We must find the gold bars before Chairwoman Seo Myeong Ju does.

B...

Now that we know that the gold bars and the ghost story are related,

we must focus on that story.

Including the one of the old building,

Byeongmun High has four ghost stories in total.

Please approve of my investigation into them.

Get on it.

Find out about the other stories first.

Yes, sir.

The ballet studio?

Why there?

They were there to see if it was really haunted,

and in the process,

they stumbled upon a model of human remains.

A ghost story?

Oh, dear. My gosh.

That thought never even crossed my mind.

A ghost...

How amusing!

I can't believe that man.

He's an odd one. I give you that.

Ghost stories related to this school?

How should I wrap up this transgression?

For now,

we'll let them be.

No one knows the school better than the students.

An unexpected solution might present itself.

Why do you want to know about the school ghost stories?

What happened last night has me intrigued.

Spill, will you?

You really must like this kind of thing.

I thought that was only for people like me.

And what kind of person would that be?

Someone with no connections and no friends.

A loner and loser who writes weird web novels.

Hey.

As if there's anything wrong with you.

Besides, friends are overrated.

Once you graduate, it's you against the world.

We're all by ourselves.

As if you'd know.

That's just how it is.

Anyway, what's the next ghost story?

Are you trying to make the ground give way?

What are you thinking so deeply about?

It's nothing.

What's your take on me?

Do I seem clueless to you?

I can't say you're quick to notice things.

Why? Did something happen?

Wouldn't you like to know?

Hello, Ms. Choi. Have you been well?

Yes, I have. I'm sorry to bother you,

but I called about my ID that the school needed.

I was wondering when I'd get it back.

The school asked for your ID?

Dong Min's friend said so yesterday.

Dong Min was receiving a scholarship and my ID was needed.

His friend as in who?

Jeong Hae Seong.

Jeong Hae Seong?

Apart from the story about the old building,

there are three others.

And one of them is about this.

The grandfather clock.

People think it's broken because it doesn't chime,

but it does so now and again.

When you're the only one left...

in the school building.

It's the story everyone's most terrified about.

"Never be alone in the school building..."

"because when the clock chimes,"

"crimson eyes will come for you."

Crimson eyes?

There were these top two students in school...

You're busted.

Are you conning people now? Get over here.

Hey, that hurts.

That's "Ms. Oh" to you!

Ms. Oh, please. That hurts.

Give it to me straight.

Why did you take Dong Min's grandmother's ID?

Her ID?

Is it over if you don't bring it?

Why do you want my grandma's ID?

You almost had me fooled.

This is a serious issue.

Be at the counselling office after school.

Me?

But it wasn't me.

I'm busy today!

Darn, the stress...

Park Tae Soo, you piece of trash.

Tae Soo...

What will become of that boy?

What am I going to do with you, Jeong Hae Seong?

Jeong Hae Seong...

Hi, starting today, I'll be your homeroom teacher.

The name is Oh Su A.

I hope we get along.

- Sure. - Got it.

Come in.

Director.

I have the analysis report from the Korea Heritage Service.

It is most definitely a forgery.

Agent Jeong's already carrying out the mission,

so I'm baffled as to how this should be handled.

You're dismissed.

Hey, Hae Seong.

The analysis report came in.

First, the pointe shoes.

They were buried there sometime in the 1950s.

As you suspected,

they were probably placed there by Seo Byeong Mun.

What about the guy who ran from the building?

I also have the blood analysis report.

It'd be faster for you to see it yourself,

so I'll send his info and photo.

Okay, thanks.

What's taking him so long?

Ms. Oh, I'm sorry,

but I left the stove on at home.

I need a drink.

Here you go. You seem exhausted.

Goodness, how sweet of you. I'll enjoy this.

You must not have gotten a lot of sleep last night.

Maybe it's because you were at the old building.

You're the one who threw...

the hammer at me.

That is one wild accusation.

Why would I go there...

when I could piss off the principal.

The tracksuit you wore last night...

How about a wager?

Did you or did you not scrape your leg on a nail?

The unused sealed entrance at the back of the old building.

That's how you got in and out.

I only have one question.

What were you doing in there?

You probably knew about the fake human remains.

- They're fake? - So you didn't know.

Goodness me.

I thought it was real.

Do you have any idea how shocked I was at first?

What kind of psycho...

Goodness.
