Produced and directed by Irish filmmaker and former BBC producer Jamie Doran, the film tells the story of thousands of prisoners who surrendered to the US military's Afghan allies after the siege of Kunduz. According to the film, some three thousand of the prisoners were forced into sealed containers and loaded onto trucks for transport to Sheberghan prison. When the prisoners began shouting for air, U.S.-allied Afghan soldiers fired directly into the truck, killing many of them. The rest suffered through an appalling road trip lasting up to four days, so thirsty they clawed at the skin of their fellow prisoners as they licked perspiration and even drank blood from open wounds.
