Duel (듀얼)

(A research on induced pluripotent stem cells, 1993)

Do you know anything about the illegal experiment he conducted?

The cloned humans created through that experiment.

If we promise each other,

then no one will know

who's me, or who's you.

To be more precise, the two cloned humans who look

just like Dr. Lee Yong-seob.

Lee Sung-joon, Lee Sung-hoon.

What if we never meet again?

Don't worry. We'll meet again.

How do you know?

Wherever you are, I'll find you.

Really?

How dare you, how dare you!

How dare you interrupt!

Because I'm your brother!

I'm your older brother.

Mom.

She's dead.

So don't cry

and wait for me.

Okay, Ik-hong. Don't worry, and go to work.

Huh?

The detective left, so it's just the two of us.

Okay, I see.

Okay.

Ik-hong said that he'll be late

because he's behind with his work.

Uh,

are you thinking

what I'm thinking?

I think this house is really quiet.

Something about the air feels empty, too.

Yeah.

I miss Soo-yeon.

The detective must've arrived home safely, right?

Probably. He must be busy

playing with Soo-yeon.

See? He doesn't even call us.

Still, he should've called us

if he made it home.

Are you disappointed?

Me? No, not at all.

You really like the detective.

No way.

I don't like him.

Ha, you're overreacting, so you do like him.

Are you in pain? Hold on.

What is this?

Take the medicine.

Here.

Thanks.

That medicine Dr. Lee Yong-seob made.

Where could it be right now?

It was 24 years ago.

If some other company or researcher got it,

it would've been developed somehow,

but no such medicine exists yet.

The one Soo-yeon got

is the only one.

Are there any more clues?

Any more memories?

No.

You'll remember someday.

I'll help you, too.

It's related to my Mom, too.

And I happen to be home

every day like this,

so I might look jobless,

but I'm actually a talented reporter.

I'm good at searching and finding.

You can trust me.

Okay, please help me.

Ms. Ryu, the talented reporter.

Please, keep it safe,

Nurse Ryu.

This is the real medicine.

Please, keep it safe, Nurse Ryu.

Yes.

I will.

It was Nurse Ryu.

What do you mean...?

The real medicine went to...

Nurse Ryu.

Your mother had it.

Doctor.

Are you Jang Soo-yeon's legal guardian?

Yes, I am. I'm Soo-yeon's father.

Is Soo-yeon okay?

Well...

She over-exerted herself today.

Soo-yeon did.

Even if she's all cured,

she should've taken it slow.

I was wrong.

She over-exerted herself today.

She rode a bicycle,

and ate too much food.

I was just wrong.

Even if she wanted to do it,

I should've stopped her.

I was simply wrong.

Am I right?

It's because she tired herself. Isn't it, Doctor?

Uh, Mr. Jang.

Yes, yes.

It seems that the leukemia

she had been fighting for a long time

is almost completely cured after the stem cell injection.

Thank you, Doctor.

But...

What do you mean, "but?"

Right now,

we found tumors

on her liver and lungs.

We tested it,

and the results show that they're malignant.

No.

Uh... I think the charts got mixed up.

Please check the chart again.

Mr. Jang, at this rate and speed,

the tumors will spread

throughout her entire body.

The chart is...

Doctor, that's wrong. Okay?

That's not about Soo-yeon.

She was having so much fun

just earlier today.

You said her leukemia was cured after she got the injection.

Then, why? What?

Where did all these tumors come from...

We can't confirm anything,

but seeing as how the cancer cells

are rapidly multiplying at an abnormal speed...

We are assuming that it might be

a side effect of the stem cell medicine.

What side effect?

Since it's a new medicine, there may be unexpected

rejection or failure in the experiment...

Don't worry about that, Doctor.

It's totally fine.

If you can just save Soo-yeon's life,

I'm ready for anything.

The longest would be a month.

It could be shorter.

No, Doctor.

Not my daughter Soo-yeon.

My daughter Soo-yeon

came back home today.

She didn't even go inside, Doctor.

Do whatever you need to do.

Please, save my daughter Soo-yeon.

Doctor...

Please,

please save poor Soo-yeon.

Please save poor Soo-yeon.

I'm sorry, we can't provide

any more treatments for her.

I'm so sorry.

Doctor...

We turned off the camera, just as you asked.

Why did you call me here?

It's nice and quiet here.

So what are you telling me quietly?

The An Hye-joo case.

It'll be better to cover it up.

The child was found dead.

- What? - Why are you so shocked?

This is not the first time a kidnapped child

was found dead.

What do you mean, "cover it up?"

Are you telling me to cancel the investigation?

Even the culprit is dead. What more can you do?

Do you know who the culprit is, too?

Of course. An Jeong-dong's mistress.

So make sure you silence everyone

before it gets messy.

How can I silence

a whole line of detectives?

That's why I told you to

work on this case with

Mr. Jang Deuk-cheon from the start.

It's hard at first,

but it's easy after that, isn't it?

You teamed up with Jang Deuk-cheon

and did it before.

Shut up, you bastard!

I don't trust you anymore.

Tell her to come, too.

Tell Choi Jo-hye to come here!

It won't be easy because of that incident.

The results were disastrous.

I know.

It's not easy.

Which is why An Jeong-dong paid a lot,

asking for help.

Shove it into Jang Deuk-cheon's mouth,

and you eat it, too.

How much longer must I perform tasks like these?
