Brilliant yet emotionally scarred mathematician Tom Jericho is called in to solve an enigma code and prevent a tragedy. A convoy of Allied ships is sailing across the Atlantic into enemy waters. If the British break the code, they will be able to discover the positions of the German U-boats and prevent any casualties. Tom joins forces with plucky Hester Wallace, room mate of his former sweetheart Claire, to solve the conundrum.
