Devil and the Deep

Sturm is in charge of a submarine, and believes his wife, Pauline, to be having affairs with other men. He drives her out of the house, and she then spends the night on the desert with Semper. The submarine is about to sail, and Pauline rushes on to the ship to warn Semper that her husband will try to kill him. Sturm deliberately causes a collision, which causes the sub to sink. However, Semper rescues everyone, but leaves Sturm to perish with the submarine.
