During World War 2, the Nazis had secret codes that contain information about strategic attacks, bombing run, U boat assault and e.t.c. Alan Turing, a mathematician genius was hired into a British Intelligence Agency for cracking these Nazi’s codes. Unfortunately, he needs to defeat the Enigma, which is a cipher machine used for protecting military communication by the Nazis during the war, but people claims the machine to be “unbeatable”. Turing and his team will analyse the Enigma code by building a machine that will read the millions millions of settings at once, that machine is also known today as the “computer”. This film tells the story in the perspective of the future (after World War 2) in 1952 with Alan Turing restating the events of his past in an interrogation room after he was found to be a homosexual and sent to prison.
