The acknowledged guru of psychedelic drugs, Timothy Leary claimed to have learnt more about himself the first time he ate magic mushrooms than in all his years as a psychologist. Described as "the most dangerous man in America" by the judge who imprisoned him in 1970, his mission was to turn America on to psychedelics. This programme explores the motives, morals and influences of the man who urged a generation to "turn on, tune in, drop out", and became demonised in the process.
