Narrator/Host

Former Special Forces soldier Jason Fox, who you may know from his now work on TV, said during a documentary that he created on his return to Afghanistan was that part of PTSD, which is what he was diagnosed with, is knowing you won't relive the moments you felt most alive.

And for some people, journalists, documentary filmmakers, war correspondents, this pull is just as strong because they choose to return again and again and again.

Sean Langan chose it over and over again.

Afghanistan, Iraq, the most dangerous places on earth.

And each time he came home, something inside him whispered, go back.

At one point during the documentary Fighting the Taliban, you have this conversation with this British soldier who is talking about how nobody understands what they've been through.

It was just such an honest moment you had with this guy.

It was so emotional.

And you could see he was pretty broken, I felt.

He'd had enough, I felt.

But he was there and he was doing his job.

I wondered if your experience of it is the same as theirs.

Because obviously, I mean, you don't have a rifle in your hand, but you are there with them through everything.

The bullets flying, the bombs dropping.

And I wondered whether it was the same for you and why you kept going back.

Chapter four, The Mad Muller.

Sean's documentary, Meeting the Taliban, is a hit amongst the audience and TV executives alike.

It would go on to win the Rory Peck Award in 2007.

The Rory Peck Awards have honoured the skills and bravery of freelance journalists worldwide for more than 30 years.

And off the back of its success, Sean is approached with a pitch for a new TV show, a sort of follow-up documentary.
