I'm in Iraq.
I've come because of a woman called Shireen.
She's 23,
and was forced to be a sex slave for Isis.
But now she's escaped and wants answers.
To find them,
Shireen's taking me to one of the most dangerous cities in the world,
Mosul, where Shireen was raped for years.
And, until a few months ago, it was the heartland of Isis in Iraq.
I've never made a journey like this.
There's a body there.
That was one of the most remarkable moments of my life.
I'm not scared of you.
Shireen's search for justice is going to bring us
face-to-face with Isis.
After my last trip to Iraq, I heard about a Yazidi woman
who was held captive for two and a half years
by the so-called Islamic State.
Shireen and I are on the way to Mosul, where her abuse took place.
Last time she was here, Isis were in control.
Now she's coming back on her terms.
Shireen, this must be so strange for you.
This, presumably, is a million miles from how you remember Mosul?
When I was here last year, the main message was,
"Do not go anywhere near Mosul."
But there are still unexploded IEDs, booby-traps.
Yeah. Why are you laughing at me?
While the war against Isis in Iraq is over,
Shireen's journey is just beginning.
She's determined to tell the story of what happened here.
Why are you coming back? Why are you doing this?
Shireen's going back to the places where she was held
by an Isis family.
There's a house nearby where she was kept for months
that she wants to show me.
You wanna check this house?
Joel, Shireen thinks the house directly behind us
is the house she was kept in. Are we OK to get out and have a look?
ON THE RADIO: Yeah, just two secs.
This one? You OK?
Are we allowed to come in? Is it possible?
THEY ANSWER IN THEIR OWN LANGUAGE
Yeah, thank you. After you.
Isis stamp? This is definitely the place?
Hello. Hello.
Shireen is racing from room to room, but upstairs
is the most important place to her.
Was this your room?
On the other side of the room,
her Isis captor's initials are still on the wall,
written by his wife.
So this was Saif?
And his wife?
Why do you think she wrote those letters up here?
The owners of the house, who were forced to flee by Isis,
have now returned.
They're horrified when Shireen describes what happened to her.
You are surprised to see Shireen back here?
Hey. How you doing?
Oh, girl.
Mosul is still dangerous so we can't spend too long in one place.
Shireen is a Yazidi,
a minority religious group that Isis enslaved in August 2014.
To trade them as slaves, they built markets.
The last time she saw her friends and family was at one market nearby.
What would happen in the hall?
In Mosul, Isis turned a wedding hall into a slave market.
In this video, they openly debate the price of sex slaves.
So this was it?
In this spot, up to a hundred women and children
were sold at a time.
Around 3,000 Yazidis are still missing,
many of them now inside Syria.
Today the market has been obliterated,
destroyed in the fighting to retake the city.
OK. Are you OK to leave? Are you happy to go?
OK, let's get back in the cars, then, girls, OK.
Shireen.
Shireen. I'm sorry to interrupt.
Our security adviser's saying that we have to go
because things are semi-kicking off again in Kirkuk,
so we need to get through the checkpoints.
It's taken a lot of courage for Shireen to return here.
She's frustrated we're having to leave.
She's pissed off.
Yeah.
I'd rather her be pissed off than in bigger trouble
in a couple of hours' time.
But, basically, we've had information
saying that we should start making our way back.
So we have to go.
I'm sorry. I'm sorry to rush you.
Have we any idea why the checkpoint called us?
Fuck.
Welcome to Iraq.
Tensions are rising in Iraq at the moment and fighting is threatening
to close the checkpoint that we need to get through to get to our base
in nearby Erbil.
If they shut it, we'll be stuck in Mosul for the night.
So we've been told to get out.
OK. That's us out.
I'm forgiven.
The battle to retake Mosul was brutal.
And when the fighting came closer to Shireen,
Isis moved her across the city.
She ended up trapped in the heart of it as Isis fought to the death.
She wants to show me where she miraculously escaped
under heavy bombardment.
Just three months ago, there's no way on this Earth
I would have been able to come here with Shireen.
There's just no way.
A few days later, we go there with a military escort.
Isis members are being hunted,
bombs still explode, and booby traps litter the streets.
Thank you. How's that feel, OK?
Yes, thank you.
Joel...
Ugh! You'll be fine.
I'm feeling completely overwhelmed.
So, there's... Are these the Americans?
I'm married, yes.
I'm married. Married.
For marriage. The commander says things are quite calm at the minute.
But I want this to be as quick as it can be.
For obvious reasons.
In and out.
I am married.
SIREN
God, look at this. It's just painfully sad, isn't it?
To see such complete devastation.
And it's never ending.
It's like road after road.
So just in front now,
they're turning the armoured vehicles around
in the case of IEDs, explosives.
Every single movement, like, every step you take, in this environment,
has to be considered.
The old city of Mosul has been obliterated
and nobody knows just how many civilians were killed.
Some estimates have it in the tens of thousands.
But the fighting saved Shireen.
When Saif was killed, she managed to finally escape to the Iraqi forces.
Now she wants to find the house that she fled from.
As we park up, a man emerges carrying a stretcher.
He's just dug his only son out of the rubble.
So, Shireen, we're to stay on this,
on the tough ground, on the concrete.
Fucking hell.
There's a body there.
Can't believe that.
There's two Isis...
..two Isis corpses just to the right of me.
Fuck.
Just two seconds.
OK?
One minute, darling.
Sorry.
It's the smell, isn't it, as well?
Shireen, do you recognise any of this?
Tell me what it was like to live amongst this, in this.
How many times did you try and commit suicide here?
Tell me a little bit about Saif and his relationship with you.
What was he like as a man?
The Iraqi commander doesn't want us to ask any personal questions,
even though Shireen wants to talk.
Shireen's trying to tell her story, but she's been silenced.
And now the commander decides we have to leave.
What's the problem?
No, can I... Can I speak to you?
We're not here to embarrass her.
Look, can I explain the situation to you?
No. I have a relationship, an existing relationship...
No, no, no. Oh, this is madness.
I have an existing relationship with Shireen.
No. Shireen wants to talk.
Shireen wants to talk.
A soldier comes up behind my producer and pushes the camera down.
Thousands of women and children were raped by Isis, but in Iraq,
it's a culturally sensitive topic.
The commander lost many men defeating Isis,
men who ultimately enabled Shireen to flee to safety.
But today, Shireen's words are too much for him.
The frustrating thing is
you've got to dance to their theme tune, because what am I going to do?
Piss him off when I'm stuck in West Mosul?
Oh, I'm so sorry, I'm so sorry.
While we're driving away, the commander has a change of heart
and takes us to a place where we might be able to spot the house
where she fled for her life.
OK, so, we think we might be in a location
where we can spot the house.
Where?
This one? Yeah.
Shireen, you seem in good spirits.
So, what, today's a celebration?
Seeing the house destroyed means a lot to Shireen.
In some ways, it's like she's been set free again.
But Shireen wants to see for herself that Isis members
are facing justice.
This building behind me,
this is where they're interrogating Isis suspects.
What punishments do they deserve?
We have a saying, Shireen, an eye for an eye.
Do you agree with that?
So, this is pretty insane.
Basically, we're about to sit in on a genuine interrogation
with an Isis suspect.
The judge is going to determine whether or not
he thinks he was complicit, he is guilty. If that's the case,
he'll go to another court and, more than likely...
..he'll be given a death sentence.
In just eight months alone,
this court has investigated 5,500 Isis suspects.
It feels cramped and chaotic.
The camera's not allowed inside, but Shireen,
our translator, and I are.
As we go inside, we come face to face with a young guy.
He's been accused of being a member of Isis.
His job, guarding a base.
Shireen is fixated as the interrogation unfolds,
listening to every question and answer.
But for this young guy, in only 20 minutes, his fate is decided.
That was quite possibly one of the most remarkable, surreal...
..moments of my life. Sat face to face with this young lad,
who looks like he doesn't have a clue what's going on.
It's more than likely he will be sentenced to death.
And I just don't really know how I feel about any of it.
Outside the court, Shireen appears to have changed her mind.
Perhaps an eye for an eye for this low-level member isn't the answer.
I'm not sure the kind of justice she wants is happening.
I didn't expect you to be able to see the bigger picture
in the way that you do, because you've been so hurt.
So, I just...
..you're a trooper, Shireen.
OK?
As we go to leave, a man approaches us.
Yes.
Sorry?
By who?
I think I understand what you're saying, you think that your brother
was an innocent man and he has been confused with an Isis man?
Are many people in your situation,
they have no clue where their relatives are, their family members?
It's common?
We've no way of knowing the true identity of his brother,
but it's clear the man faces a difficult task finding him.
Thousands of Isis suspects have been detained and it seems like the law
is pretty black and white.
If there's any suspicion you're Isis, you'll be dealt with.
Having had a chat with that guy,
it's becoming increasingly clear that this is such a grey,
difficult area.
You know, trying to find out who's innocent and who's guilty.
And that judge, he sounds completely overwhelmed.
He said he himself can be dealing with up to 30 suspects a day.
And inevitably, in this situation,
some people who haven't done anything
are going to be found guilty.
So justice in Iraq is far from clear cut.
While we're back at the hotel, we get a call.
An Isis commander who's being held at a maximum security prison
has agreed to talk to Shireen.
We don't know under what conditions he's agreed to speak to us,
but he's admitted to some of the most horrific crimes.
Come in.
Come into my home.
So, tomorrow the plan is to go and see an Isis fighter.
His name's Omar. He's 21.
He was instrumental in...
..the persecution towards Yazidis.
So he himself had three Yazidi sex slaves.
And he was also involved in slaughtering the Yazidi men.
And so it's really, really important that you want to...
You want to go through with this
and you want to have that conversation with him.
What kinds of questions do you want to ask him?
Today, Shireen has a chance to get answers.
Inside a military base, we wait for the prisoner.
He may have to choose his words carefully under the watchful eye
of the security forces.
But we're about to come face to face with Isis.
He's going to be brought to us.
This is the room that they've given us.
That will be OK?
I'm assuming he'll just plonk himself there.
You're a strong girl, Shireen.
Hello.
This is my friend Shireen.
She is from Sinjar.
She's a Yazidi woman.
I'm sure you're familiar with that community.
And she has some questions that she would like to put to you,
in terms of your involvement and why you did what you did.
900?
How many women, how many children
do you think you've raped over the years?
What was going through your mind? Talk to me.
Tell me what you're thinking when these girls are screaming
for you to stop and you don't, you continue?
Omar, our time with you is up.
We have to leave. Is there anything else you'd like to say
before you're taken back to your cell?
No? I'm not scared of you. I don't think Shireen's scared of you.
I don't... I don't think you have to apologise for that.
It's worth you knowing, you know, Shireen is a very, very strong woman
and she's working on rebuilding her life and she has a future
in a way that you, perhaps, don't.
Thank you for your time, Omar.
I understand to a certain extent that he was probably forced to kill.
But nobody held a gun to his head
and forced him to rape all of those women. Nobody.
That was... That was his choice.
That came from his set of decisions.
And that's why I feel the way I do about him.
It's time for Shireen to return home to the camp where she now lives.
Long drive.
You got your music?
Yeah?
Take care.
See you later.
OK?
You stay strong.
Yeah.
I am particularly shit at goodbyes. I always...
CAR HORN BEEPS
I think in my heart, you know, really and truly,
she will only be at peace
when she knows what's gone on with her sister.
And no one at this moment can help her with that, so...
But I think it's just worth remembering, you know,
there are thousands of Shireens,
there are so many Yazidi girls who have absolutely no idea...
..where their loved ones are.
They don't know if they're dead or alive.
They don't know if they're still being held.
And I can't imagine how unbelievably difficult that must be to live with.
In many ways, I wonder if Shireen wasn't just on this journey for her,
but for all the Yazidis who endured the genocide,
including those yet to come home.
