Enigma

About “Enigma”

In 1943, during World War II, much of the Nazi Enigma code has been broken, but the Shark cipher, used by German U-boats, remains a threat. A secret team of British cryptographers works to crack Shark, and mathematician Tom Jericho succeeds. However, the Germans discover that Shark has been broken and change the code. As an Allied convoy travels through the North Atlantic, Jericho's ex-lover Claire disappears under suspicion of being a Nazi collaborator. Jericho struggles to break the new code, but he faces a terrifying realization: there is a traitor among them.
