Nova program Decoding Nazi Secrets is the story of Churchill's secret weapon in the war against the Germans. Churchill had assembled a group of American and British mathematicians, crossword enthusiasts, linguists, and chess champions to crack a secret coded Nazi device. The German message-coding machine Enigma, appropriately named, was thought to be "unbreakable." Decoding Nazi Secrets tells its story through interviews, dramatic reenactments, and newly discovered film footage. Meet "Colossus," the world's first computer and the machine that was powerful enough to crack the "invincible" Nazi codes of Enigma.
