Alan Turing is the genius British mathematician who was instrumental in breaking the German naval Enigma Code during World War II, arguably saving millions of lives. Turing's achievements went unrecognised during his lifetime. Instead he ended up being treated as a common criminal, for being homosexual at a time when homosexual acts were a crime. In 1952, he was convicted of 'gross indecency' with another man and was forced to undergo so-called 'organo-therapy' - chemical castration. Two years later, he killed himself with cyanide, aged just 41. Alan Turing was driven to a terrible despair and early death by the nation he'd done so much to save.

The highs and lows of Alan Turing's life, tracking his extraordinary accomplishments, his government persecution through to his tragic death in 1954. In the last 18 months of his short life, Turing visited a psychiatrist, Dr. Franz Greenbaum, who tried to help him. Each therapy session in this drama documentary is based on real events. The conversations between Turing and Greenbaum explore the pivotal moments in his controversial life and examine the pressures that may have contributed to his early death. The film also includes the testimony of people who actually knew and remember Turing. Plus, this film features interviews with contemporary experts from the world of technology and high science including Apple co-founder Steve Wozniak. These contributors bring Turing's exciting impact up to the present day, explaining why, in many ways, modern technology has only just begun to explore the potential of Turing's ideas.
