One day while scuba diving off their grandfather's boat, teenage brothers Christian (Robert Hansen) and Ask (Ralf J. Hollander) discover the infamous German submarine U-461, which sank off the Danish coast at the end of the Second World War, killing everybody on board. After glimpsing the face of a living baby boy preserved inside a medical container in the vessel, Ask becomes haunted by the boy's spirit. Meanwhile, a group of salvage contractors led by a former Nazi (Baard Owe) will stop at nothing to get ahold of the ship's valuable cargo.
