Summary: In the midst of World War II, the battle below the seas rages. The Nazi's have the upper edge as the Allies are unable to crack their war codes. That is, until a wrecked U-boat sends out an SOS signal, and the Allies realise this is their chance to seize the 'enigma coding machine'. But masquerading as Nazi's and taking over the U-boat is the smallest of their problems. The action really begins when they get stranded on the U-boat.
