The Imitation Game

In 1951, two policemen, Nock and Staehl, investigate the mathematician Alan Turing after an apparent break-in at his home. During his interrogation by Nock, Turing tells of his time working at Bletchley Park during the Second World War.

In 1928, the young Turing is unhappy and bullied at boarding school. He develops a friendship with Christopher Morcom, who sparks his interest in cryptography. Turing develops romantic feelings for him, but Christopher soon dies from tuberculosis.
