Afghanistan's Opium Trail
Over 90% of the world's opium now comes from Afghanistan. In this shocking new film, we ride the drugs caravan, from cultivation, to process, to market. On route, we lift the curtain on the hidden world of the drug barons; learn how to process heroin in the crudest of laboratories and encounter deadly gunfights on the Iranian border.
