In the rubble of Kabul's Old City live a feral population of drug addicts. It's here we first meet Reza and Hussein, shooting up amidst a minefield of old needles. Like many of the city's addicts, they picked up the habit in Iran. "These are the people who really had a lot of problems because they were living in asylum", explains Habibullah Qaderi, Minister for Counter Narcotics. Lured back from exile to a country unable to support them, they slid deeper into addiction. But now, Reza and Hussein have decided to get clean. As drug use is prohibited by Islam, rehabilitation programmes are bottom of the list for state funding. The only place in the country they can receive treatment is Kabul's Mental Health hospital. As Reza and Hussein are shown around, they hear the screams of a female patient undergoing electro shock therapy in the next room. Despite all obstacles, the brothers are committed to getting clean. As Hussein states: "If you ever see me in any of the drugs dens again, shoot me."
