Codebreaker tells the remarkable and tragic story of one of the 20th century's most important people.  Alan Turing set in motion the computer age and his World War II codebreaking helped turn the tide of the Second World War.  Instead of receiving accolades, Turing faced terrible persecution. In 1952, the British Government forced him to undergo chemical castration as punishment for his homosexuality.  In despair, Turing committed suicide.  He was only 41 years old. Documentary elements seamlessly interconnect with drama scenes in Codebreaker to offer a three dimensional picture of Turing, his accomplishments, his tragic end, and his lasting legacy.
