During the worst days of World War II, the British government asks the mathematician Alan Turing to unravel the mysteries of the German Enigma encryption machine, an impossible task to accomplish without the invaluable information that Hans-Thilo Schmidt, a disenchanted but greedy German citizen, had been handing over to the French secret services since 1931.

For 20 years, theirs was an ideological duel between two visions of Communism; a political duel, a duel for power, and above all, a duel to the death. By having Trotsky exiled and finally assassinated, Stalin gained sole control of Russia and became the unassailable dictator of the country.
