Silent Witness

I want to be a pathologist, Nikki,

.. but I have to go home.

Luisa went somewhere she should not have gone.

Don't make the same mistake.

This is my baby, Nesto.

All these people have been taken by the cartels?

Where is Luisa? Where have they got them?

If we give up, if we stop...

They'd give them back.

Ernesto, Luisa, the others?

I'd give my life for him.

Eva... Eva you're confused. Nikki's at the compound.

She was with me. She was here.

Nikki!

Oh, don't ring off! Wait!

Don't go!

'Save your energy.

'You will need it.'

Who are you?

Why are you doing this?

'You'll need your oxygen, too, so stop screaming.'

Get me out!

Get me out of here!

'You'll need water.

'There's a bottle by your feet.

'Only take sips.'

Emergency services. What is it?

9-1-1.

Oh, Jack.

What is it?

Oh, no, think.

0-7-5-1-7...

I'm buried.

Shit. Shit.

Rewired.

Hello.

Over. Down.

Can we get it in there, OK?

Tell me. Tell me again.

I was driving. I looked over to Nikki, she was falling asleep.

We were on the road to Santa Dominga and...

Oh. Jet-lag.

Sorry.

Then what?

I don't know.

How's your head?

He must have been hiding in the back. He must have hit me.

I shouldn't touch.

It's your car, you're all over it.

Yeah, we can get some fibres off this.

Yes.

And then what do we do with them?

What else can I do, Eva?

This is my fault.

If I had stayed home with her.

It hasn't been used since midnight, before they left.

It's hers?

She's really gone, isn't she?

Why take her?

I don't know.

Why take her, not Eva?

I mean, Eva's the prize, isn't she?

I don't know.

Maybe they made a mistake. Maybe, maybe they thought she was Eva.

What do they want?

- What do they want? I asked you a question! - I don't know!

They don't want you here.

They don't want anyone to help us.

That's better.

See, you always find the right thing to say in the end, don't you?

How do you do it?

Your childhood sweetheart is kidnapped, murdered, God knows what.

All this shit swirling around you

and you walk through it untouched.

- The eye of the storm. - Really?

- You know that, do you? - No. Nobody does.

Nobody knows you, not really. You make sure of that.

You're angry.

What have I got to be angry about?

Luisa's father, on the other hand, I imagine he's very angry.

I mean, you... you let her go out there day after day, right?

She called you that day.

She needed you. Where were you?

Did you love her?

I mean, really?

Or was she just another member of the fan club?

I'm sorry.

No, no. I'm sorry for you.

For Dr Alexander.

She wanted to be a part of something.

Now she is.

No!

650 by 850.

Roughly 2,300. Oh, shit.

So, 1,270 litres of air.

Only 21% is oxygen.

267 litres.

Say, at rest, a person consumes 0.35...

763 minutes, that's 13 hours. I've been in here...

.. maybe two hours.

So, 11 hours.

But the box isn't empty.

I'm in here.

The average volume of the human body is...

That's 13 litres less oxygen.

35 minutes less.

Can't panic.

Wasting air.

Slow breaths.

Where's your friend?

The pretty one.

Prick.

If you know something...

How can I know? I'm in here.

You know where Luisa Herrera is.

Sure.

She's in the ground.

You know, if Dr Alexander doesn't come back,

I might just put something else in this needle.

No, you won't.

She would...

.. but you wouldn't.

This isn't good for us, either.

We want to find her, too, but we're stretched.

37 students were kidnapped from a college in Culiacan last week.

You have a lot to deal with.

A lot to turn a blind eye to.

Have they been in touch?

Have there been any demands?

No. Not yet.

Do you think they will?

She's a foreigner, she has money.

Or maybe they've already got what they want.

We've got nothing. Nothing, Thomas. Don't even know if she's still...

I'm at Heathrow, Jack.

I'm on my way. I'll be there in less than 18 hours.

What do the Foreign Office say?

The embassy in Mexico City has been instructed

to prioritise Nikki's case...

- But? - There's some hostage situation, oil workers in the Gulf of Mexico.

But they've promised they'll get people up to you soon.

What does soon mean?

24 hours.

24 hours?

Be positive, Jack.

When they realise they've got the wrong person, they'll send her home.

She was taken here?

Yes. These are all the known cartel safe houses,

including the one you were sent to.

Gustavo and his men had all the main roads blocked within minutes,

so we work on that presumption, that they had an hour and

a half to take her wherever they were taking her.

We'll work in a 60km zone, south along the coast,

inland to the east.

- Why not north? - Because they knew we'd be coming from there.

They sent us to that fake tip-off.

We have to make rational presumptions.

We cannot search everywhere.

That still leaves all these...

We found 4X4 tyre tracks leading off the road.

There's nobody around.

Not that we can see, anyway.

The only obvious skid marks match the tread pattern from Eva's car.

And nothing to pin down the vehicle they took Nikki in?

There were other tyre tracks about 20 metres behind Eva's car,

but the tread pattern is FS-470,

which suggests a late-model saloon, not a 4X4.

So, we've got...

Very little.

Sorry.

This isn't your fault, Jack.

I'll check those tread patterns, OK?

Who are you?

What have you done with her?

Jack...

Nikki?

Nikki?!

Jesus!

Nikki, where are you? I'll come and get you.

- Jack... - Nikki, thank God you're safe.

How did... How did you...?

Nikki, are you OK?

Can you talk?

No.

Nikki, are you hurt?

No, I...

Just tell me where you are.

Nikki, is there... Is there someone there with you?

No.

Can you tell me where you are?

What can you see?

Nothing.

Any detail, the room you're in, anything at all.

I'm not in a room, Jack.

So where are you?

I'm under the ground.

What?

Buried.

What?

In some sort of box.
