Sinopse
Enigma transports us to March 1943 and the desperate race against time that was waged at Bletchley. His hero, Tom Jericho, has been called back, while recuperating from a nervous breakdown, to try to crack Enigma before German Uboats sink hundreds more American convoys bringing suplies and munitiobns to Europe. If he solves the puzzle, thousands of Allied troops will live. If not, Jericho and his peers face the reponsibility for a massacre.
