This drama tells the tale of real life mathematicians/cryptographers, led by Alan Turing (played by the excellent Benedict Cumberbatch), working in secret for the British government during WWII to break the Nazi’s Enigma communication code, which was considered practically unbreakable. The movie does a good job of portraying the tension the team must have felt as they worked against time to break the code and turn the tides of war. I expect your attention will be held throughout given a fascinating story and strong performances from all of the actors.
