- Is she following us?
- No.

- Why was she aiming at me?
- I think it's because of that video.

- What? Is that chick a hater?
- Rebeca, that girl is an assassin.

I saw her kill my friend in cold blood
at the university.

She killed professor Barrera.
And she thinks I can identify her?

Exactly. Could you? Do you have
any videos showing her face?

- No, no, they got deleted.
- What do you mean?

They got deleted.
Why haven't you gone to the police?

I can't go until--

- Damn, it wasn't her.
- I have to go.

- Wait, you can't leave me.
- Go to the police, tell them everything.

Unless that chick catches me first!

Do you have any devices
that can be tracked?

No. I left my computer at the coworking
space and the chick took my phone.

Okay.

Okay, come with me.

MOM: WHERE ARE YOU?
SHARE LOCATION. DENY

- Are you coming or not?
- Yes, coming!

DAY ONE

I want all the witness' statements
on my desk.

Why are you in my office, Chief Inspector?

He's going rogue, doing whatever he wants.

- Calm down.
- He questioned Damián Diskin before me,

he didn't tell me about the location
of my suspect.

Calm down, it was an order,
Chief Inspector.

My unit had already identified
Ulises Albet,

and placed him near the university
the day of the attack.

How did you get to him?

The intelligence services
have our own resources.

I understand. What I don't get is why
there wasn't a search warrant issued?

- Are you all right?
- Well, miraculously. What is it?

Just a warning: Moreno isn't happy.

Well, got anything on the girl
who was with Albet?

- No, she hasn't returned home.
- We'll surveil the place.

It's done. There's a patrol in the area,
and her roommates have been notified.

Okay. What about the motorist
who nearly killed me?

I've checked, it's a cloned license plate.
Who do you think it could be?

A professional, for sure. Let's go.

Salvador. Come with me.

- Good luck.
- Thank you.

Close the door.

- What the fuck happened?
- I had a lead and I followed it.

You had a lead?
Then inform us and step aside.

- It was a great lead, Ricard.
- I want you to go home.

Take a couple of days off.
Rest, recover and--

- I don't need to rest.
- Well, you're going to, Salva.

It's not a suggestion, it's an order.

They're sending me home, I'm off the case.

- What? Are you serious?
- Keep me posted, okay?

- What do we do with this?
- He's off the case.

What's in Barrera's computer
is none of our business.

- Where did you get that?
- Our friends in the unit shared it.

- Have you checked it?
- There are over 50,000 files.

We were better off
when they didn't cooperate with us.

- Hello?
- Perdomo, it's Salvador.

Man, Inspector Salvador.
You must want something.

I have some files about biotechnology
and stuff. I need to understand them.

Say no more, I'll go to your office.

No, I'm already on my way.
I'll be there in 15.

Main floor.

To what do I owe the honor
of you coming to see me,

- and not the other way around?
- I like the views.

Of course. Who are you hiding from?

Morcata sends love, by the way.

Agent Morcate?
Is she still in love with me?

- You wish.
- I'm still hopeful.

And what can I do for Morcate?

I need you to translate these files
from a victim,

about biotechnology, that stuff.

- There's been a murder? What happened?
- Who said anything about murder?

You're a homicide inspector,
I doubt you have a tax fraud victim.

I can't talk about
an ongoing investigation.

- I know.
- How long will it take?

- The bare minimum--
- Good.

I'll wait here.

Sorry, honey, I can't talk right now.

Salvador.

This is very interesting.

Studies on the iris,
the gateway to the frontal lobe.

A gateway to the brain.
The brain, the great unknown.

The owner of these files studied
the eye-brain connection.

I don't get it, sorry.

"The eyes are the windows to the soul
where love peeks amazed."

Poets had already realized
that the eyes are a gateway to the brain.

And science has started using it,
especially neurophotonics.

A branch that combines optics
and neuroscience.

They use light to study, diagnose

and sometimes even treat
nervous system disorders.

But many of the advances
are still only theoretical.

It seems that Mr. Barrera was taking
these investigations to another level.

Okay. Well, thank you very much.

Can I keep this to look into it
in more detail?

- Call me if something catches your eye.
- Yes.

Don't lose it,
or Morcate will kill us both.

I don't know about you,
but if it's her, I'll let her.

Right, I'll tell her you're a romantic.

- Come on.
- Yeah, yeah.

What is this place?

It's where my company used to be,
the one I started with Samuel.

Paula, a friend from college, lent us
the money to buy our first computers.

And what was the company?
Buying and selling stolen cars?

Well.

- Are you a programmer?
- I was. I left everything behind.

I hadn't spoken to Samuel in ten years.

And when you saw him again,
he got killed in front of you? Why?

I mean, why did you come back?

Samuel messaged me, he wanted to see me.

He wanted to give me an encoded file
for me to interpret.

- And did you see the code?
- I didn't get the chance.

- Why did you stop working together?
- That doesn't matter.

- Why did he think you could help him?
- Do you always ask so many questions?

Mainly when someone's trying to kill me.
Yeah.

I don't know, they killed him
before he gave it to me.

- All I know is there's a copy.
- Here?

I thought so, but I can't find it.

Okay, I didn't know
Professor Barrera much,

but I suppose if he wanted
to save a file and hide it well,

there are millions of hiding places here.

It's like in the movies:
a cereal box, a toilet tank.

Professor Barrera looks so young.

Who is she?

Anna.

- Anna?
- Anna was my sister.

She died.

I'm sorry.

If you're sleeping over,
that couch is more comfortable.

A little early, isn't it?

- It depends on what for.
- To go to the palliative support group,

- the meeting is at 3.
- Holy shit.

It'll be good to see other cases,
see what can be done.

- It's no use if I go alone.
- Okay, so don't go, what can I say?

I won't give up, I hope you won't either.

Come on.

Come on. We'll go to the next one,
I promise.

How about you take a few days off?

I'm ahead of schedule with the project,
I can disappear.

- We could go to Girona, like when we met.
- No can do. My suspect has escaped.

I'll see you tonight, okay?

But promise me
that when you close the case,

we'll go together for a few days,
we need it.

- Okay, I promise.
- Okay.

- Bye.
- Bye.

Can you find any reference in Samuel's
emails to the code he wanted to show me?

There are 12,560 emails mentioning
the word "code."

Do any of them contain the word "code,"
and the name "Pandora file" or "Ulises?"

There are zero messages
that fit the criteria.

Okay. It's a dead end.

Back to places
where he could've hidden the file.

Any locker from a gym,
a club or something like that?

Samuel? Go to the gym?

Okay, forget it.

Who are you talking to?

Uli, you didn't tell me we had a visitor.
I would've showered.

With three-in-one, of course.

It wasn't funny when he was alive either.
This is all we have left of Samuel.

The best of him.

Is it an AI assistant?

It's definitely artificial,
not sure it's intelligent.

Wow, and I'm the one with the bad jokes.

- Does he know where the file is?
- Not at all.

He should know where Samuel was
before he died.

Did Samuel carry any exercise tracker?

He was wearing a smartwatch.

Can you tell me what his route was
before we met in his office?

He went straight to university, no stops.

He arrived at the office
and never made it out.

I think I know
where he could've hidden it.

Wait, wait! After your little show,
I don't think you'll go unnoticed.

Did you put on a show? A flash-mob?

- I'll go.
- No, we'll both go, I'll stay outside.

Okay, but wear something to hide
your face. A baseball cap or something.

7 NEW TEXTS FROM MOM
DO YOU NEED TO CALL A TAXI?

Hello, Mommy. How are you?
Forgive me for abandoning you.

I'm super busy with "talent."
I'll call you ASAP, okay? Bye.

- Shall we?
- Coming.

CONNECTION LOST

What do you think?

- She turned on the contact lenses.
- Yes, but she's turned them off again.

- Shall we?
- Coming.

We've got a location.
Have you notified Damián?

No, I was about to.

Damián, we have a location.

YOUR BREAKFAST
THE MOST IMPORTANT MEAL OF THE DAY

Mom.

Mom.

- Thanks for breakfast.
- It's important to eat. Good morning.

I'm sorry about yesterday.

Were you arrested?

- What?
- Were you arrested? Or kidnapped?

Or did you have to save a baby
from a fire?

Otherwise, I don't get
why you couldn't answer.

- It was the baby in the fire.
- Right.

No, no, really, I should've let you know.

No, no, you had to save the babies.
I forgive you, I suppose.

- And where were you?
- I went to work.

What? You already have a job?

No, but I'm working
on the investigative report.

I've interviewed friends
of the murdered professor.

Enough, enough. Why are you
in such a hurry to start working?

Relax a little bit.
We should have fun together first.

- Together? You are never here.
- I know.

- What? You have to go?
- Sorry.

No, don't worry.
I'll keep working on my report.

Hello? Who is it?

Hello, am I talking to Inspector Salvador?

Yes, what's up?

I hope you are well.
Mr. Diskin would love to see you

and he has an open slot
in his schedule today at 6 P.M.

Could you come to our facilities?

All right, I'll be there.

Thank you, Inspector. Have a nice day.

- What should I look for in there?
- A computer.

Didn't the police take them?

Yes, they must have taken
the ones that were in use.

But there was another one
in the office, in a display cabinet.

An old computer?
You think he kept the file there?

Yes. Sharing that computer,
Samuel and I became friends in college.

I printed out a copy of the access code
to Samuel's office.

You'll need it to get in.

He probably has several files
on the computer.

The file you have to copy
is named "Pandora."

Once you're in,
look for the display cabinet,

it's in front of the servers
that exploded.

The computer was there
the day I went to visit Samuel.

In the other hallway, I don't know.

Why is this door open? Go get the keys.

The police told us
to keep the office locked.

They're in my office.
Go on, or we'll get in trouble.

- Did you copy everything?
- Yes. Okay, what do we do now?

Give it to me, I'll go to The Workshop
and figure it out.

You think I've come this far to leave
without knowing what's in it?

You're crazy. Let's go.

What are you doing? Where are you going?

Let's go. Hey.

What happened to you?
Why does someone, a tech genius,

suddenly leave everything
behind overnight? Don't you miss it?

If you think I'm going to stop asking
questions, you're dead wrong.

- Thank you for coming, Inspector.
- Thanks.

Take a seat.

Do you have any information on the case?

Do you know how penicillin was discovered?

By chance.

And by chance we made
a big breakthrough in neurophotonics.

Do you know what that is?

The combination of neurology and optics.

- Using light to modify the brain.
- Not modify, but intervene.

We're still in the experimental phase,

but we have high hopes
for our clinical trials.

What does that have to do
with Barrera's death?

Nothing. This is about you.

I know you have an inoperable tumor.

Are you confessing a crime
of personal data privacy violation?

I want to offer you
that treatment, Inspector.

Why?

Because you only have a few months left,
and this treatment could cure you.

Why?

In a few days, I'll launch something
I had been working on

for a long time with Samuel.

Day One, a technology
that will change the world.

You still haven't answered.

And I don't want anything
to cloud that launch. Do you understand?

Because some things are priceless.
Like life.

All you'll have to do is inform me about
your progress on the case, that's all.

I see.

Thank you very much, Mr. Diskin,

but it's a no,

- I can't accept.
- May I know why?

I won't give you information about a case
you're suspiciously interested in.

Very well.

I just wanted to extend your life.

Sure.

Expectation and mystery surround
Damián Diskin's new Day One device.

Mere days before it hits the stores,

we know nothing about a product
that promises to be revolutionary.

The secrecy surrounding
this new innovation

from Diskin companies seems to be
their successful marketing campaign.

I'm going to the gym.

Don't do it for me,
you know I love your tummy.

Yeah, not everyone won
the genetic lottery like you did.

- What are you up to?
- Just working from home.

You complain a lot,
but you live much better than me.

- Oh, yes, sure.
- Yes, yes.

- See you later.
- See you later, honey.

Alexa what's Day One?

Day One is a new device based on a
technology created by Diskin Biotech.

Although it promises to be revolutionary,

nothing is known about the product
ahead of its global launch.

When will it launch?

In three days.

Is there any connection
between Samuel Barrera,

Ulises Albet and Diskin Biotech?

Searching the International
Patent Registry,

I found that in 2016 Samuel Barrera sold
a patent he shared

with Ulises Albet to Diskin Biotech.

What was the patent for?

In an iris analysis system
for emotional modulation

using artificial intelligence.
Like an emotion translator and modifier.

Thank you, Alexa.

Paula, have you seen my headphones?

Honey, I think I know what's going on
with Ulises.

I'll be back in a couple of hours.

Please don't get involved.
You lent him your car and tablet.

The police may think you're helping.

Ulises didn't ask for any of that.
And I need to help him.

Come on, what are you saying, dude?

I'm so hyped on whatever Diskin
is launching.

It blows my mind
that all of us are talking about something

that we don't know what it is yet.

I'm dying to try Day One. I about to
stand up and go to line up at the store.

Follow me, please.

First of all, I don't want Paula
to get in any kind of legal trouble.

I think Paula went to meet Ulises Albet.

- Do you think she might be in danger?
- No, no, Paula trusts Ulises.

But she should be back at her office,
and she's not there.

Do you know where your wife
might be meeting Ulises Albet?

I think so.

Make it quick, Elena.

Paula Castell's husband was just here.
We know where she's meeting Albet.

Okay, tell me where.

Salva, you're risking
permanent suspension.

Yes, but you can't go over Moreno.

Stay put, okay?
Go on, send me the location. Bye.

We're not going anywhere,
Salvador wants to go himself.

What is it? Don't you care?

- You'd better get used to it.
- I won't.

Well, I wish you luck, Corporal Corbella.

Why are you so afraid
of pissing off the boss?

Look, we're playing the same game,
but we have to look for new rules

to be allowed to play the match,
and this time, we didn't make the team.

What do you mean?

I thought that using soccer terms
would make you understand.

Uli?

Have you finally named the place?

Samuel says "The most promising
startup in Barcelona."

- An honest name.
- As your boss--

Semi-boss. Without my savings,
you wouldn't have computers.

Remember me when you become billionaires.

- No, I'm not playing against you anymore.
- Come on, we'll win this time.

Damn, Uli, you really suck.

- Let's do an angry face.
- And now like Samuel, know-it-all.

I love you.

Uli?

Don't turn around
or I'll blow your head off.

Paula Castell?

Ulises?

Hello? Police!

Ulises.

Hello?

Ulises!

Paula.

Ulises! Ulises! Watch out!

Let's not get dramatic,
let's all stay calm.

Please leave us alone.
We didn't do anything.

No!

Salvador to HQ, I need backup now!

Help! Help!

Help!

Police!

Help! Fuck, shit

I'm coming in!

What do we do?

Step away from the door, I'm coming in!

No, don't shoot.

Don't move.

Ulises!

Drop the gun.

Drop it.
