During the early years of World War II, the legendary and lethal Nazi U-boats spread terror from beneath the sea. Now, more than fifty years later, on a salvage operation off the coast of Florida, the Hardys plunge into the rusting hull of one of those awesome submarines...and discover that the terror still lives!
