In 2009, Swansea drug agencies reported a 180 percent rise in heroin use, and it's visible on the city's streets. Early one morning we meet a young, homeless couple named Amy and Cornelius in a city centre alley. As heroin-addicted alcoholics, they're smack in the middle of two of South Wales's most harrowing epidemics. An award-winning look at a generation lost to heroin, as told through the tragic love story of Amy and Cornelius.
