It is February 1942 and the war in the Atlantic looks grim for the Allied convoys. The 'Great Blackout' has started, leaving the spy centre of Bletchley Park in Buckinghamshire at a loss as to what the Nazis are planning. Winning the Battle of the Atlantic will surely give Hitler a final victory. And who can stop him?
