In between filming his American documentaries and pissing off the Scientologists, Louis Theroux found time to make this documentary which sees the reporter visiting the liver centre at King's College Hospital, London. Louis meets alcoholics in need of special treatment for the damage heavy drinking has done to their bodies, as well as talking to patients about their battle with addiction and its impact on their health. He also meets the doctors trying to save them and discovers the consequences for the families involved.
