Where's Professor Han?
Beom Gyun is losing his memories.
That technology can convert memories into videos and edit them.
It's right in that room, in that house.
- Woo Jin. - You might be able to find...
something in Gyodeok-dong.
This is my memory.
No one including Professor Han would give up.
No, they could never give up.
You're Human B, right?
I'm the only one who knows how to activate it.
What do you want?
I'm suspended?
This is a seizure and search warrant.
Someone is trying to cover this case on purpose.
It's possible Beom Gyun is also their target...
because he's the most certain evidence.
How could you lose them?
Professor Han threatened me, and I told him I'd convince you over.
Did Dad really leave nothing behind?
It was that.
I need it to save Beom Gyun.
Do Jeong Yeon and I have to go?
Kim Gyu Cheol here.
We need to stay here. That's the only way we'll find Woo Jin.
You're with Lee Hyeon Seok all the time.
There must be a time where you're not aware of what he's doing.
Where's Woo Jin? You know where he is, don't you?
Woo Jin is certainly dead.
Then why is Human B still working?
If Woo Jin is the system itself,
he's definitely inside Human B. We need to get inside.
I'm sure Lee Ho Soo knows where they are.
Check his memory video.
It's a virus. It's hacking into our security system.
He wants me to insert a virus into his care chip.
- We don't have time. - Thank you, Ho Soo.
Go and check the circulator right now.
The supercomputer is useless without Woo Jin.
If you want to save Woo Jin, restore your memory first.
- What's going on? - We have a situation.
The supercomputer has crashed.
Something must've happened to Woo Jin.
No way.
Is that you, Woo Jin?
Is there...
really no way now?
(Episode 11)
Kim Gyu Cheol here.
Dad.
June 20, 2008.
The final entry for the BETA Project.
I found it.
I found it, Beom Gyun.
(Part 1: BETA Project)
I discarded all the research data today.
BETA Project is over.
My colleague, Dr. Han Yong Woo, wanted to continue the research.
But I've concluded that human beings should not acquire this technology.
Dr. Han, Byul's memory management technology...
should only be used for trauma treatment.
It can do much more than that.
Dr. Kim, human beings are imperfect.
Greed, anger, fear...
These emotions get in our way.
And all those emotions come from memories.
So what do you want to do?
If we delete all harmful memories with this technology,
we can build a world free from crimes or wars.
Even imperfect human beings can build a perfect world.
That technology will be owned by imperfect human beings.
Someone will try to monopolize the technology.
Human beings will try to manipulate and control others' memories.
That hasn't happened yet.
We can't stop the progress now just because we're afraid.
Dr. Kim, think about it.
It's nothing, Byul. Dr. Han is overly enthusiastic.
I want my memories deleted.
I didn't think about human beings' desires.
If the technology can be abused, I'd rather destroy it.
That is why I deleted all the memories Byul had,
who taught us the memory control technology.
Byul wanted me to.
Dr. Kim.
Where is Byul? Where is she?
It's too late now. I deleted all her memories.
No. I'll restore them.
Tell me where she is.
It's over.
Gyu Cheol.
You might even die.
If this goes wrong, both you and I might die.
This might put me in danger.
But as a human being, not as a scientist,
I did what I had to do.
Whoever you are, if you're looking for my data,
please stop.
Byul's technology does not exist anymore.
And it should never.
There is no research data...
left anymore.
There is no research data left?
(Circle)
Dad, I think Beom Gyun is having a seizure.
Okay.
- Please take us to Gyujin Hospital. - Okay.
Beom Gyun, hang in there.
There was no research data in the first place.
What should I do with Beom Gyun now?
So what does he want?
Like what your dad did,
he wants to do a research on Byul together.
He said that's the only way to treat Beom Gyun.
So he wants me to bring Jeong Yeon and Beom Gyun to him.
Woo Jin, Beom Gyun is having a seizure. Come to Gyujin Hospital.
What?
- Oh, no. - Shoot.
- Save him, please. - Shoot.
- Beom Gyun. - Charge 200 joules.
- Beom Gyun. - Clear.
Shoot.
ROSC achieved.
Beom Gyun.
- Check the vitals often. - Okay.
Doctor, is Beom Gyun okay?
He's stable now.
Does Beom Gyun have epilepsy?
- No. - Then...
it must have been the blue worms.
He had a grand mal seizure and a respiratory arrest.
That's what led to a cardiac arrest.
I might not be able to save him when he has another cardiac arrest.
Can't you operate on him?
The worm has moved to a trickier place.
A craniotomy can be risky.
We have to find out about these worms quickly.
No, we don't have time for that.
Those who invented these worms will have to take them out.
(Dad)
What are you doing?
He might tell me how to save Beom Gyun if I go.
What my dad wants are my memories.
I can go to him.
I deleted all the memories Byul had, who taught us the technology.
Byul wanted me to.
You can't.
There is no other way. I have to go.
There is a way.
- Like what? - I found...
my dad's research data.
This is what Professor Han wanted.
This will do.
So trust me and just wait for me.
There is no research data left anymore.
Why are we having a class in a karaoke room?
We're not having a class today. I have a favor to ask.
What is it now?
Last time, you said you'd do anything for me. What did you do?
- What do you want? - I want to skip four classes...
without my mom knowing.
Here is a burner phone.
What are you going to do with it?
We shouldn't leave any traces from now on.
Both you and me.
- Professor Park... - Hyeon Seok.
We're about to reach the peak of neuroscience.
Professor Han said...
it was possible to convert memories into videos.
I might be able to...
acquire that technology soon.
- Sorry? - Woo Jin...
and Jeong Yeon are all I need.
Woo Jin?
June 26, 2017. 3pm.
He was watching everything.
This is actually good.
(Park Dong Geon)
Kim Gyu Cheol here.
June 20, 2008.
The final entry for the BETA Project.
(Kim Woo Jin)
Hey, Woo Jin. What's this clip about?
Is this...
Yes, I found my dad's research data.
I'll hand this over to you.
On one condition though. Please let him know.
Condition? What should I tell him?
Beom Gyun must get his surgery first.
You want to exchange Gyu Cheol's research data with his surgery?
Yes. If he does the surgery on him, I'll hand over the research data.
If I give him the data, he won't need Jeong Yeon and me anymore.
What if he refuses?
He'll probably want to check the data first as well.
He can hold me hostage.
What?
Professor Han even installed a surveillance camera at my old house.
He'll certainly know...
that I'm staying as a hostage.
All right. I'll pass the message along.
Woo Jin, are you really going to be okay though?
Professor, I'm sorry that I got you roped into this.
Don't say that. It was my fault that I couldn't stop Professor Han.
Yes. I'll help you in any way I can.
Just hand over the research data. Then we can put an end to this.
Will everything really be over if we get the research data?
Of course not. This is only the beginning.
We'll get our hands on the data and keep Woo Jin too. He's the key.
Jeong Yeon will be next.
The BETA Project will be reborn from my hands.
This is Park Dong Geon.
We need to stage a situation.
- Hello? - Hey, Woo Jin.
Professor Park?
Whose number is this?
Human B gave me this phone to ensure no traces are left.
They're extremely thorough.
What about Professor Han? Have you gotten a hold of him?
Yes, he'll accept your proposal.
Gwangsang Apartment demolition site at 4pm.
The doctor who will do the surgery will go straight to the hospital.
You have to make sure to bring the research data.
Okay?
Got it.
Will Professor Han let me go...
just because I've handed over the data?
He knows that I'm the key to the system.
Will I be able to put and end to this mess...
and come back in one piece?
("Easy, Fun Baking")
I'll never do anything that would worry you.
I'll...
never leave you alone.
Beom Gyun.
Everything will be fine, right?
We can save Beom Gyun?
I found Dad's research data.
I'm handing it over on the condition that Beom Gyun gets surgery.
Are you sure you can trust them though?
I'll go with you.
It's okay. Professor Park will go with me.
You should stay here to let me know when the surgery starts.
And please keep updating me until it's finished.
When it's done, please move him elsewhere as soon as possible.
We don't know what they would try to do to him.
The research data is the only thing Professor Han wants.
Everything will be over once I give it to him.
- All right. - Be really careful.
Nothing will happen.
Take good care of Beom Gyun, okay?
Woo Jin.
Are you all right?
Hey, your face looks really handsome seen from this angle.
Don't joke with me. I'm not in the mood for that.
Beom Gyun.
You're going to undergo surgery.
Beom Gyun.
What is this?
It's for my grandma.
It has some things she needs and money for the sanitarium fees.
I've been neglecting her as I've been preoccupied with Beom Gyun.
Please look after her for me.
She likes you more than me, you know.
Are you sure that thing will resolve everything?
Of course. Professor Han has been dying to get his hands on the data.
Shouldn't I go with you?
If you come with me, things might get more complicated.
Stay with my grandma.
I'll join you later so that we can run away together.
Why are you telling me to stay there if you're really going to be okay?
Just in case. That's all.
I'll get going.
I'll...
see you very soon.
I'll be waiting.
Bye.
It's okay. Come in.
Where's the data? Let's see it.
I've never seen a cross-shaped one before.
That's right. It's Gyu Cheol's USB flash drive.
Hello?
The doctor is here.
He started the surgery.
Okay. Please call me when the surgery is done.
We're good now, right? Give it to us.
I'll give it to you after I check and make sure the surgery is done.
We have to know if it's real.
I'll give it to you after the surgery.
Give it to me, you jerk.
Have you lost your mind?
Do you have a death wish?
Stop.
Stop!
Whose orders are you following?
I'm sorry.
You brat.
Woo Jin.
Why are you complicating things?
You're driving me crazy.
Are you one of them?
Not at first.
Actually, I'm still not one of them. But...
I need that data, Woo Jin.
You understand that...
everyone wants that technology.
Then you must know everything.
The room, the technology...
I'm the only one who has seen the research data.
It's all in my head.
And it's all in the house I used to live in.
I saw my dad's research data.
I can show you my memory videos. So please...
make sure my brother's surgery goes well.
Then I'll show you my memory videos.
If I refuse or die,
everything will be over.
Yes, Hyeon Seok.
Go to the house in Gyodeok-dong and get the hard drive.
Yes.
Beom Gyun's surgery is over. He survived.
Okay. Please take care of him.
Come back here. Is everything okay?
Don't worry. I'll be right back.
Satisfied? Beom Gyun is safe now.
Let's go.
So where is...
the research data?
June 26, 2017. 3pm.
Get him!
- Get him! - Move!
Follow him! Hurry!
Stay in the house.
When you hear a howling sound, turn off the electricity.
Leave after an hour.
And then go straight home. Do you understand?
- What is this all about? - It's important to me.
Gosh, I'll just listen to some music.
(From Woo Jin)
By the time you're watching this,
you must be on your way to the sanatorium.
I've found out everything.
By the time you're watching this,
you must be on your way to the sanatorium.
I've found out everything.
It was your choice to delete all your memories.
My dad and Byul decided to destroy her memories.
So live as Jeong Yeon. It was your choice.
You are Han Jeong Yeon.
You have her memories.
To me, you're not Byul anymore.
You're Jeong Yeon.
I'll go back to Jeong Yeon.
Hide yourself as soon as you watch this.
Even if...
something happens to me,
you have to do as I say.
You must protect yourself until the end.
Darn it.
This kid is making my life so difficult.
Hey. Come on out, okay?
If you keep this up, you might actually die.
Hey, your dad died because he was like this too. Do you understand?
Woo Jin. Kim Woo Jin!
Gosh, where did this rat go? Woo Jin.
Let's not make this difficult, okay? Come out.
Woo Jin.
- Goodness. Hey, Woo Jin... - You scum!
This is getting fun, don't you think?
Just follow your dad's path.
Die. Just die. Die!
Hey.
Hey, I told you not to kill him.
Let go. Let go!
I apologize.
Gosh, that kid is putting me through this ordeal.
Seriously.
That brat.
Stay still, you punk.
Woo Jin.
Let's not exhaust ourselves here. Do you have the data or not?
There's no such thing.
Then let's get out of here quietly.
We should watch your memory video and find Jeong Yeon.
- Don't you dare touch her! - You little...
Woo Jin.
I'm trying to do this for the betterment of mankind.
Don't you want to see...
how advanced this world and science can be?
Don't try to justify yourself. You just...
You just want this technology.
You're crude.
What's wrong with that?
Take him.
- Get up, you punk. - Let go.
Come on, you jerk.
- Let go! - Get him!
Why are you guys standing around? Go get him!
That little...
Hey!
You better stop.
- Stop! Woo Jin! - Woo Jin.
- Woo Jin! - Stop right there!
Get him!
- I absolutely won't get caught. - Woo Jin!
I'll go back at all costs.
Jeong Yeon...
Even if something happens to me,
you must protect yourself until the end.
Open the pouch.
Wait for me.
Wherever you are,
I'll come find you.
Woo Jin...
- Beom Gyun. - Hey, Woo Jin!
Woo Jin! I'm here.
Beom Gyun.
I'll see you very soon.
I'll be waiting.
Woo Jin.
Open the door.
What?
No way.
Woo Jin.
Is that you?
Woo Jin.
Is that you, Woo Jin?
Are you...
really Woo Jin?
Jeong Yeon.
Are you really...
Woo Jin?
What happened? Where am I?
Let's get out of here first.
Are you really Woo Jin?
Who are you?
Jeong Yeon, what's going on right now?
Who are you?
I...
I'm Beom Gyun. It's me, Beom Gyun.
Beom Gyun?
Find the circulator.
Find him right now!
(Circle)
(Year 2017)
It's been 2 years and 6 months since he got into an accident.
His organs are slowly deteriorating.
I can't be sure of how long he'll continue to live.
Woo Jin can't die.
Gyu Cheol's research data didn't even exist in the first place.
And Jeong Yeon has disappeared. She's nowhere to be found.
The only thing we have left is Woo Jin...
and this cube.
If he dies, it'll be the end of this project.
When will the doctor arrive?
He's coming to Korea next week.
He's the only hope we have.
That's illegal.
But it's not impossible, is it?
You are the first doctor in the world...
to ever succeed in animal cloning.
But cloning has never been attempted on a human being.
Officially, yes.
But unofficially,
it's under research by all the scientists in the world.
We have a funding, human resources,
and technology to support you.
Everything will be kept a secret.
You know that one day, human cloning will become legal.
And when the day comes,
you will gain the title of being the first doctor to succeed.
I hope that you'll accept my offer.
Please.
Professor, he did it.
He succeeded in making a clone.
Let's test it right away.
What will you do with Woo Jin if the test result is successful?
We should let him go. He's been through so much...
until now.
This makes no sense. 20 years have passed,
but how can you still look the same?
20 years have passed?
Are you really...
Beom Gyun?
Yes...
Joon Hyeok.
Are you really...
Woo Jin?
I went to meet Professor Han after parting with you that day.
But Park Dong Geon was there.
He was the one who planned everything.
I tried my best to escape and go back to you.
But I got into an accident, and I woke up today.
And now, you're telling me that 20 years have passed?
That makes no sense. Then why do I still look the same?
Does that mean Woo Jin came back to life?
Is he even still alive?
Yes, he is alive.
Jeong Yeon, come on.
Don't joke with me. I'm not in the mood for that.
What is this?
What's wrong?
It's nothing.
Hey, open the door.
- We need to get out of here first. - Who's inside? Open the door!
Hey, open up!
Who's there?
Let's go. Hurry!
Wait here.
You know what will happen if you make a sound, right?
Explain what happened to him.
Tell me what happened!
He's Circulator number three.
Then...
does that mean...
Yes. It's exactly what you think, Jeong Yeon.
That thing over there is Woo Jin's clone.
Woo Jin...
died...
15 years ago.
Woo Jin...
is dead?
Woo Jin...
is dead?
That can't be.
I remember everything.
I got into an accident and woke up today.
I remember everything!
How can I be a clone?
That's because we inserted his memory into your brain.
What does that mean?
We succeeded in cloning him,
but we couldn't connect the cube with his clone.
You know that star-shaped ornament that had a memory cube inside?
His memory.
His memory was the answer.
That cube...
would only connect when it could read...
Woo Jin's bio-information and memory.
Do you get it now?
You're not Woo Jin.
You're just a key that's needed by the supercomputer.
You're just a component.
Chief Hong, I think that's Human B.
Are you sure they're in Human B?
My gosh, I saw them talk through their radio.
Okay. Let's go.
I can't believe this.
This can't be true.
(Director Code 9: 2nd floor, Section A)
I just got a code nine from the director.
Everyone, go to Section A on the second floor.
Back off.
Drop your guns. Don't move.
Do you think you'll be able to escape?
Shut it.
Drop your guns.
Joon Hyeok.
Hey, Joon Hyeok.
Detective Hong.
Woo... Woo Jin?
Open the door!
You're Woo Jin?
- Who are you? - What's going on?
How can this be?
How can my teacher look the same when I've grown so old like this?
Joon Hyeok, what's going on right now?
What happened to Woo Jin?
We can't stay here. Let's get out of here first.
Block that door for us.
- Okay, Chief Hong. - Let's go.
Woo Jin's dead?
So are you telling me that he's not Woo Jin?
Woo Jin died?
But he looks exactly the same as Woo Jin.
Do you not know what a clone is?
Of course, he looks the same.
Then that means he's Woo Jin.
Hey, it's me. I'm Dong Soo. Can't you recognize me?
- Dong Soo? - I'm Dong Soo.
See? He recognizes me.
He's Woo Jin. He's my tutor, Woo Jin.
Yes, but your actual tutor is dead.
I know, but he recognizes me.
Do you think this makes any sense?
You've never even met this guy before.
Detective Oh is right.
He's not Woo Jin.
Right? He's a clone, right?
- He can't be Woo Jin. - But he remembers me.
He's not Woo Jin.
Woo Jin's dead.
You can't call him Woo Jin just because he looks like him.
My younger brother and your tutor is dead.
That thing...
- isn't Woo Jin. - He still remembers everything.
Woo Jin told me that...
I'm Han Jeong Yeon because I'm living with that memory.
You are Han Jeong Yeon.
You have her memories.
I lived as Han Jeong Yeon until now because of what Woo Jin said to me.
So that also means he's Woo Jin.
He has Woo Jin's memories, so he's Woo Jin.
No. Woo Jin's dead.
That hand...
isn't the hand that I held.
And that body isn't the body that I embraced.
He's just Woo Jin's replacement.
If he's Woo Jin,
then what does that make my dead brother?
He...
can never be Woo Jin.
You're not Woo Jin.
The supercomputer has lost its connection with the circulator.
Tell me everything that could happen.
The calming care system will get disconnected from everyone.
Then people will start committing crimes,
and we won't be able to control any kind of unexpected incidents.
We also won't be able to block outsiders from entering our city.
That's not all.
The most dangerous thing is that...
people will start regaining their blocked memories.
How long will it take for their memories to come back?
That has never happened ever since Smart City has been built.
So it's very hard to predict.
It depends on what kind of memory it was that got blocked,
how old that person was when it got blocked,
how strongly traumatized that person was because of that memory,
and the gender and age of that person.
Everything I just said will act as a variable.
Does that mean we can't predict anything at this moment?
In the worst case, we'll have to make Circulator Four.
That will take at least one year.
If this continues within that year, Smart City will collapse.
Then I guess we have an answer.
Openly search for Kim Joon Hyeok, Bluebird, and Circulator Three.
Put them on the wanted list for being terrorist suspects.
Hurry up and find them as quickly as possible.
It doesn't matter if you harm Circulator Three...
as long as you keep him alive.
(Wanted)
Kim Joon Hyeok and Bluebird. Where are they right now?
They are not terrorists.
The real culprit who's bringing...
chaos to Smart City is Minister Park Dong Geon.
What?
Park Dong Geon is the chairman of Human B.
Human B is blocking people's memories.
Do you expect me to believe that?
Park Dong Geon is the one who deleted Mayor Yoon's memory.
Stop talking nonsense!
Tell me Kim Joon Hyeok and Bluebird's...
current location.
(Wanted)
I don't quite get it yet.
Is it really...
2037 right now?
Woo Jin.
Did they successfully finish his surgery? Did he regain...
his memory?
No. Beom Gyun woke up after 10 years.
When he woke up, he watched your memory video.
I should at least leave my memory behind.
This will at least help him remember me,
even if he forgets everything else.
Beom Gyun...
can't remember what happened on the day you disappeared.
The memory video you had left behind didn't include that part.
Does that mean he tried so hard to look for me...
with such an incomplete memory...
for 20 years?
Joon Hyeok, I don't get what's going on right now.
He looks like Woo Jin, and he has Woo Jin's memory.
Those two look like they're still living in 2017.
Joon Hyeok, Park Dong Geon just set an alarm for counter-terrorism.
You, Woo Jin, and I are wanted for being terrorists.
We need to get out of here with Woo Jin.
If he gets caught, they'll connect him with the supercomputer again.
He's not Woo Jin!
- Joon Hyeok. - Do you still not get it?
That thing is just a component made by Park Dong Geon.
Joon Hyeok.
Are you saying we should escape without him?
If Woo Jin gets caught, he'll have to live as...
Human B's slave for the rest of his life.
He'll have to constantly remember only the worst memories.
- That has nothing to do with me. - Joon Hyeok.
I don't know if I should say this,
but if he's so important to Human B,
wouldn't it be dangerous for us to take him with us?
So what are you saying?
Are you saying we should leave my tutor behind?
He's not your tutor. He's a clone.
A clone? Are you done talking?
My gosh, you jerk. The real guy is dead.
That guy's a clone. Am I wrong?
Hey, stop fighting with each other.
- Woo Jin. - Are you okay?
Hey, you look really handsome from down here.
My gosh.
Don't joke with me. I'm not in the mood for that.
Beom Gyun.
You're going to undergo surgery.
Beom Gyun.
What's this memory?
I've never seen this on Woo Jin's memory video.
Why am I suddenly remembering this?
Where are you going?
I'll go.
You're right.
I'm not Woo Jin.
I'm not your brother either.
So everything will end if I go.
I'm what Park Dong Geon wants.
Please run away with Jeong Yeon.
When you do,
you can live as Kim Joon Hyeok.
Also, tell Jeong Yeon to continue living her life as Jeong Yeon.
Just forget about everything else.
Beom Gyun.
What...
What did you say to me that day?
What did you say to me...
20 years ago before I got my surgery?
That wasn't me, Detective Kim.
That memory was just inserted in my brain.
Answer me! What did you say to me?
"I'm..."
"scared."
Beom Gyun.
- I'm scared. - Because of my surgery?
It'll go well. Don't worry.
Okay.
I'll be back.
- Where are you going? - I won't take long.
Okay, see you.
Beom Gyun.
Don't forget me, okay? I won't forget you either.
Why would I forget you?
Okay, I'll remember everything.
"Beom Gyun."
"I'm scared."
"I'll..."
"be back."
So were you...
on your way to meet Park Dong Geon that day?
Were you on your way to...
give them...
Dad's research data so that I could have my surgery?
Is that why you were scared?
Is that why...
you were scared?
I'm sorry.
I shouldn't have sent you alone that day.
I'm sorry, Woo Jin.
I'm sorry.
I'm sorry. I'm really sorry.
Beom Gyun.
I shouldn't have let you go alone.
I shouldn't have sent you there.
Beom Gyun.
I'm sorry.
(Circle)
Why are you here alone? Did they abandon you?
A memory video?
The cyber crime unit? Why am I getting sent to such a random unit?
What's going on?
Joon Hyeok and Woo Jin have both disappeared.
They abandoned you.
- Where's Jeong Yeon? - We're in trouble!
If only I can catch them, I can do a lot more than this.
The SWAT team is here. Does that mean they're going to kill us?
What else can we do than to kill them?
There's a 50 percent chance. We need to try everything.
Just wait. You'll be able to meet Jeong Yeon and your brother again.
We need evidence to bring Park Dong Geon down.
