content: A young mathematical genius, Tom Jericho, is returning to the British code-breaking center during World War II after he has been sent away due to personal problems. They are now trying to crack the new code that the Nazis use when they communicate with their U-boats, since it seems like the Nazi's are now trying to attack convoys coming from the US with food, ammunition, and other equipment. The British Intelligence Service is very suspicious of how the Nazi;s knew that they had cracked the former code and they begin to scrutinize Tom's past. Enigma can be described as a cat and mouse game that has a soul, but lacks flesh.
