Disheartened when his story about Canadian snipers possibly mutilating corpses in Afghanistan is buried, Luke (Nick Stahl) quits his job but is even more determined to return to Afghanistan to get the real story. With his offbeat buddy, Tom (Nicolas Wright), tagging along, Luke returns to Afghanistan and intends to gather enough evidence to get his old story into print. But he soon finds that the country is an even more dangerous place than when he left. To make matters worse, his old friend and fixer, Mateen (Stephen Lobo) has been hired away by Luke's journalistic nemesis, Imran Sahar (Vik Sahay). Soon the trip for Luke and Tom in Afghanistan turns into a surreal and perilous adventure, a journey into an alternate reality, filtered through a haze of gun smoke. They encounter Taliban raids, bombings and unfinished business with an Afghanistan businessman. Luke still makes his way through the wilderness with Canadian troops and Arabian guides to find out if his story is true or not. In the end, he realises that the rumour about Canadians mutilating fingers is a lie and that his people still have some morality in this war torn land. Just as he is about to leave, He and Sgt. Rick (a Canadian soldier who is the leader of the squad with whom he had been travelling) come under fire from a Taliban sniper, but the Taliban runs out of bullets and walks off, while Luke thinks he killed him.

The documentary is largely based on the work of award-winning Afghan journalist Najibullah Quraishi. In late 2001, around 8,000 Taliban fighters, including Chechens, Pakistanis and Uzbeks as well as suspected members of al-Qaeda, surrendered to the forces of Northern Alliance General Abdul Rashid Dostum, a U.S. ally in the war in Afghanistan, after the siege of Kunduz. The program recounts that several hundred of the prisoners, among them American John Walker Lindh, were taken to Qala-i-Jangi, a fort near Mazar-i-Sharif, where they staged a bloody uprising which took several days to quell. It shows footage of Walker Lindh being interrogated by CIA man Johnny Micheal Spann, taken just hours before the latter was killed. The programme describes how the remaining 7,500 prisoners were loaded onto sealed containers for transport to Sheberghan prison. The journey was to last several days in some cases; many of the prisoners did not survive it.
