Good evening. Tell me.

Sanchez! Come here.

Inform Inspector Moreno.
There's something here.

DAY ONE

Look how happy are you for being in
the middle of my investigation, Inspector.

Even if he's suspended,
he does whatever he fucking wants.

- Am I wrong?
- I have some days off work.

Sure.

How did you know
the suspect would be there?

Because of the murdered woman's husband.

Did the husband call you on your days off?

Yes.

So, no one in this headquarters
knew anything.

- No one.
- Of course.

If someone had taken a statement
and hadn't reported to the unit,

there should be a file created on them.

It was only me.

What do we know?

The gun is being examined, but
the fingerprints are from Ulises Albet.

- He was carrying it.
- What did the girl say?

We're waiting for the public defender
to start the statement.

But she must have said something
in the car, right?

Yes, that Paula Castell was killed by the
same person who tried to run over me.

I don't understand
how could you have missed it.

You didn't pursue her, did you?

Well, my priority was to attend to
the victim. Not pursuing the suspect.

- What do you think is going to happen?
- Nothing, a little reprimand.

We should have gone ourselves.

I don't think they would turn a blind eye
if we were over Moreno. Salva knew it.

You've been alone a lot,
surrounded by men.

You're too scared to screw it up.

Stop with this nonsense and...

Look, there's the public defender.
Walk her to the room.

Let me see if the ballistic report is
ready and do some true police work.

You owe me one.

- Cristina, how are you?
- I'm good.

- The lawyer is here.
- Good.

Where are you going?
I'm going to interrogate her.

I arrested her, so I interrogate her.

This is related to the University case.
Maybe next time, Salvador.

But it is a homicide
that doesn't follow the modus operandi

that brought you here, Inspector.

And that involves the Homicide Unit.

When Salvador finishes interrogating her
you can try it,

if there's something left.

Don't say a word.

Not a word.

- What the hell happened?
- I should be the one asking that.

The police went to the location you sent.

I don't know
how the police knew the place.

I want my full payment.

How would I know that if I pay you now
you'll continue with the job?

How did you know
where Ulises Albet was hiding?

If I was evil-minded,
I would think you want to fuck me up.

- Finish what you started.
- I won't work with someone I don't trust.

Find Albet.
Don't kill anyone else until you find him.

I won't have any loose end.

The inspector will take a statement.

You're not under arrest,
you can refuse to answer any question.

You can take your things.

They can't hold you here
more than 72 hours

without making some kind of accusation.

- Do you understand?
- Yes.

- Okay? Any doubt or question?
- No.

We can begin.

Why did you stay with Ulises Albet
and not go to the police?

I believe him.

And I was scared that the woman
who attacked us

at the coworking space would appear again.

Why do you think Ulises is innocent?

Because I saw
that he didn't kill the woman. I saw it.

When we arrived, she was dead.

And I'm sure
he didn't kill Samuel Barrera.

What did he tell you about Samuel Barrera?

They were partners. They were friends.

They hadn't seen each other for a while.

Did he tell you why?
Why they stopped seeing each other?

Or why did they meet
in his university's office?

You spent a lot of time with him.

- He had to tell you something.
- You don't have to answer.

I don't know. I don't know.

The only thing I know is that Ulises
is in danger.

There's someone
who wants to accuse him, even kill him,

and I think it is the same person
who chased us and shot me.

There is news. Ballistics confirmed it.

The gun of the scene is the same
that was used to kill Samuel Barrera.

Moreover, one of my agents found
an identical detonator

to the one used in the University' attack.

You don't have any idea
who you've gotten yourself mixed up with.

That gun belongs to the killer,
not Ulises.

She ran away before you arrived.

Do you know what charges you can get
for being an accomplice?

Inspector, besides the fact that
interrupting a statement like this

is unusual, you don't have any proof,

or you would have already submitted it
or arrested my client.

You can interrupt the statement
whenever you want.

I want to go home.

Can we speed things up?

- She doesn't have a criminal record.
- We can't.

You can go whenever you want.
You just have to sign the statement.

- Where do I have to sign?
- Come with me.

Police are no closer to discovering
the true identity of the culprit,

whose only clue is the book he left
at the crime scene:

Henry David Thoreau's Walden.

However, this book was not found
at the scene of the recent murder

of BSC director Paula Castell.

Police are continuing their
investigation...

- Honey.
- ...into last night's incident

and hope to determine
if the two murders are related.

They're looking into whether these deaths
are related...

Why did you wait for me?
You should have gone to sleep.

Are you okay?

Where are you going?

I shouldn't have come.

It's only this campaign, I promise.

Honey, it's obvious you don't live here.
You just sleep.

There's something. I know it.
Something you are not telling me.

What's going on?

I've been stressed,
but it's not because of you.

It seems like it. I should go.
Tomorrow morning I'll go to Brussels.

What? No, you won't.

You're right. This job is burning me out.

What if we leave?

What if we start all over again?

In another city or even another country.

There's nothing holding us here.

Just tell me where you want to go.

Somewhere we can start a family.

Just give me one week.

I have a second death complicating
the case.

Do you know how much trouble
we can get into?

I just gave an order
to the people you suggested.

I thought it was something simple,
not the Texas Chainsaw Massacre.

Your friend thinks
she's still working for a cartel.

Salvador is still pissing me off.
He won't leave the case.

I'll take care of Salvador.

You're in charge of the motorcyclist.
I know where to find her. Come on.

Hello, everyone.
I know I've been missing for a while.

Thank you so much for all your messages.

I just wanted to tell you that I'm okay.

And I'm waiting for a friend.

He has had some hard days

but things are going to be better
from now on, I'm sure of it.

Sometimes you think everything is over,
but you're wrong, there's still hope.

I'm not going anywhere,
I'll be here waiting for your comments.

My friend's sister was bullied
on social media,

it was the same for me.

I've never spoken about it, until now.

A couple years ago I started to receive
messages from haters

and they affected me a lot,

they were stuck in my head
and I couldn't get them out,

I couldn't escape from them.
I even met with a hater.

I thought that if he knew me,

if I talked with him, he would
understand that the hate on social media

and the anonymous hate hurts a lot.

Actually, I gave him the power to hurt me

and nobody would care.

The only thing I could do was disappear.

- Rebeca.
- Ulises!

Are you okay?

I thought you wouldn't come.
They interrogated me!

Not here. Let's go.

I watched you on live on Paula's phone.

We're not safe here.
We don't have much time left.

- I need the pen drive.
- Sure. Here.

Hey, Uli, I'm really sorry
about your friend.

I want to help you.

I appreciate what you have done,
but it's enough.

- No, no.
- It's enough.

It's not enough. Whether I like it or not
I'm also in this mess.

We need a computer.

I took it back.
Can you see I'm really in this mess?

We also need a place to hide.

- I think I have one. Should we go?
- Come on.

Let's go. This way.

Damián. Damián.

What have you've done?
What are you hiding from me?

There was another death.

PAULA CASTELL'S MURDER:
A DEADLY TRIANGLE

BETWEEN FORMER
STARTUP COLLEAGUES?

We knew his location.

How can you think
I'm capable of using violence?

Since Samuel's death,
I don't recognize you.

This can't be a coincidence.
All these deaths are related to Day One.

Samuel's actions
have brought unexpected consequences,

but you can't forget what is important.

We have 48 hours left until cities
become places without crime,

the end of the violence,
that is Day One's purpose.

Or do you want Joao to replace you?

Good. I need you to do something for me.

Technology has ended
the idea of boundaries in crime.

And that's what we are here for
and we have all the resources we need.

It's okay to have all the resources,
but it's better to have a good officer.

I agree, and I'm looking for one too.

You know where we are.

- Did Salvador know you'd be here?
- No.

- He's doing a 24-hour shift.
- No.

Yesterday he was in our office and...

I'm here to tell him something important.

I couldn't explain it to him,
here's all the information

about our experimental treatment.

About what?

The treatment for his brain tumor.

You can tell me, I'm his husband.

Of course. It's an experimental treatment,

but it can put an end
to epileptic seizures

caused by the tumor
and slow down its growth.

I hope he accepts our offer.

Tell him that Mr. Diskin
is covering the whole cost.

Nothing else.

- May I accompany you?
- No, it's okay.

You're lucky we have one room left,
we don't have them this time of the year

and less so in a week
with technological things.

We're here because of that. I was selected
for the Talent Arena's hackathon.

Very nice. You can have breakfast here
and the Wi-Fi works well.

The patio has access stairs on both sides.

There's an elevator, but it's better not
to take it, it stops whenever it wants.

There's only one rule, no parties.

Don't worry,
my brother doesn't like parties.

There's nothing to worry about, right?
You don't like parties.

No, we don't have parties at home.

- Okay, the key.
- Very nice. Thank you.

- Thank you.
- You're welcome.

- How do you know this place?
- From a party.

This place is a mousetrap.

We can go somewhere else...

Wait, is the only place
where they don't check the ID.

Yeah. Password...

Okay.

Here we go.

What is this?

Damn.

We'll have to stay and live here
if we want to understand that.

There's a folder with my name.

It's my research on emotions.

What?

Anan, what are you doing here?

- What are you doing? You have class.
- I'm not coming back.

Ana, leave Samuel's computer
and tell me what happened.

Samuel said:
"You can use it whenever you want."

You can use it whenever you want,
but not now.

Talk to me.

I developed a code to identify other
people's emotions. It's like a translator.

- An emotion translator?
- Yes.

Why would anyone want something like that?

Well, for someone who is incapable
of identifying other people's emotions.

I'm working on translating emotions
to a mathematical language.

It's going to be easier for you.
It will be a translator for you.

When I achieve it,

you'll be able to understand
what people feel when they talk with you.

Damn. I thought
you would be on the cryptobro side.

Why did you do it?

Because of my sister.
She had some difficulties.

She was very smart, but since a young age

she didn't understand reactions, emotions?

People didn't understand her either.

Anna, you can't be here all day long.

You need to go outside
and socialize with people.

I know them... here.

You don't need this.

I'm almost done with my work.

Go away.

Go away.

That's why Samuel called me.

Samuel thought that I could decode,

understand it
with the university's computers,

but this is too much.

Don't you think we can decode one part?

Even if it's only one part, it's too big,
and we only have one computer.

May I try?

Let's see?

I didn't know you use contact lenses.

Yes, a little bit of early presbyopia.
That's all.

Okay.

- Have you found something?
- Not yet.

Damián, the girl just activated
the contact lenses. She's with Albet.

I'll send you the address.

You have the real time location.
Don't fail this time.

INTRUDER DETECTED

Pick up, Lucas.

HONEY

Son of a bitch.

Calling Lucas.

Yes, honey?

- Lucas.
- Wait, I'll turn off the music.

Are you okay?

Honey?

Hello?

Hello, my love.

Is everything okay?

Yes, okay, I just wanted to know
what you were doing.

I just took a shower and I'm going out.
I'm going to meet a journalist friend.

That's nice, good idea,
go out and take your time.

Hey...

- I love you.
- I love you too.

What's going on? What?

Cava? At this time of the day?

- I messed up, didn't I? What day is it?
- You're getting away with it this time.

- About what?
- When were you going to tell me?

- About what?
- The experimental treatment.

A doctor came
to give you more information.

I can't believe it.

Son of a bitch.

What's going on?

That son of a bitch... I can't accept it.

- That's what's going on.
- Are you joking?

No.

Salva, this is an incredible opportunity,
for both of us.

This guy is in some trouble,
he's in the case I'm investigating.

It doesn't matter. Then we pay for it.

Not even if we had three lifetimes.
And not only that, but my principles.

- What?
- What about me?

Damn it, Rafa...

You can't make a decision like that
without me.

I wish you loved me half
as much as your principles.

I hope it's important.

The receptionist of a hotel called,
he recognized Ulises Albet.

- He's in a room with a girl.
- I'll take care of it.

No, I'm coming too.

Okay. I'll see you there.

I think I found something.

Did you design a chip
for your emotion translator?

No, why?

Here are some plans,
it looks like a prototype chip.

The chip is necessary
for the neural process.

We need to know where they put that chip.

It's Pandora's copy.

- We have to tell Diskin.
- No, wait.

How did you plan on capturing emotions
once they had been classified?

With the phone's camera?

It was my intention, but I never did it.
Or with glasses too.

With a contact lens?

Using the iris to reach the brain,
maybe in 10 years?

- Damián, there's a Pandora's copy.
- That's not possible.

Beth confirmed it.

Are they still in the same location?

Yes, in the hotel from the center.
They didn't move. What do we do?

I'm coming to the control room.

- You betrayed me.
- What are you saying?

Moreno is a police officer.

This bastard wanted to kill me,
not arrest me.

In my own house. How did he get in?

The police have their ways to track you.
I need you more than ever.

He's corrupt, he's going on his own.

I want three times
what we had agreed upon.

- Deal.
- Now. Transfer me the money now.

Damn it.

What?

Diskin took me to his office
to show me a new product

that will be launched,
it was called Day One.

They are contact lenses.
He gave them to me to try them.

- The ones you're using?
- Yes.

The connection is still on?

- We have to stop her from taking them out.
- Why didn't you tell me?

Make her run away. Activate fear.
Adrenaline on maximum level.

I had to sign an NDA. I'm really sorry.

Look,
they are like any other contact lenses,

but they're an amazing augmented reality.

Take them out.

Take them out.
I'm sure they have tracked us.

We didn't design them for that.
We're messing with her reality.

Rebeca, are you okay? Take them out.
They tracked us.

- What the hell is wrong with you?
- They'll be seeing what you're seeing.

- What are you doing?
- What?

- What are you doing?
- What's going on?

- Give them to me!
- You're scaring me.

Emotional overload LIMBIC system.

Damián, the adrenaline rush
is going too fast.

More.

- Take them out!
- Leave me alone!

- Rebeca, calm down.
- Leave me alone.

Take them out now! Give them to me!

Stop it! Damn it, leave me alone!
Help! Help!

That's enough.

Cerebral amygdala in the verge
of vital failure.

- Help! Help!
- That's her.

Help! Help! Help!

Rebeca! Rebeca! Rebeca, stop!

Rebeca, stay there! Don't move!
Do you hear me?

Shit. Follow her.

Ulises! Police, calm down.
Don't complicate it any further, please.

- Come with me to the police station.
- Rebeca!

- Ulises! What's going on?
- You have to arrest Diskin.

What?

Diskin! You have to stop Day One!

Move! Move!

Please!

Rebeca!

Please! Please! Please! Please!

Hey, calm down.

We have to help her.

Increase in heart rate.

Hey, please, come on.
Can you go back to your rooms?

Risk of heart attack.

Now it's enough.

We're police officers, go to your rooms.
Keep calm and go to your rooms.

- She's gone.
- Rebeca! Rebeca!

Ulises! Not now.

Go to your rooms!

Go to the exit.

Salva! Salva!

- Rebeca!
- What? What happened?

The contact lenses, take them out.

- Are you okay?
- Yes, yes.

- Yes, I don't know what is happening.
- I'll explain everything.

- Stop!
- Quickly!

What happened?

What are you hiding from me?
