Afghanistan's opium crop, harvested each year and moved north along the old Silk Road routes through Central Asia toward Europe, is the thread this film follows from field to street. Narrated by Colin Friels and produced by Chris Hilton, it tracks who profits at each stage of the trade and who pays for it, from farmers with no other cash crop to the addicts and HIV cases piling up inside Afghanistan itself. The film lays out a blunt statistic: Afghanistan and its neighbors supply around 80 percent of the heroin sold in Western Europe, and some of the men now sitting in government cabinets are the same warlords who ran the trade under different titles. Landscape footage of the mountains and border crossings frames a case about corruption reaching into state institutions and security forces along the route. The film's real argument is about priorities, that the war on drugs and the war on terror are fought in the same territory, with the same people, and that Washington has let one crowd out the other.
