Several American and British civilians are stuck in a lifeboat after their ship and a U-boat sink each other in combat. Willi (Walter Slezak), a German survivor, is pulled aboard and denies being an enemy officer. During an animated debate, Kovac (John Hodiak) demands the German be thrown out and allowed to drown. Cooler heads prevail with Garrett (Hume Cronyn) asserting the German’s prisoner of war status and he is allowed to stay.
Kovac takes charge, rationing the little food and water they have; but Willi gradually takes control away from him and is later revealed to be the U-boat captain. One morning, while the others are sleeping, the injured German-American Gus Smith (William Bendix) catches Willi drinking water from a hidden flask. Too delirious and weak to wake anybody up, Gus is pushed overboard by Willi and drowns while the others sleep. Upon waking, the others discover Gus missing and Willi is questioned. When they notice that the Nazi is sweating, the other passengers discover the hoarded flask in his jacket. In a spasm of anger they beat him up and throw him overboard, striking him multiple times to prevent him from reboarding. Musing on Willi’s treachery, Rittenhouse (Henry Hull) asks, “What do you do with people like that?”
The survivors are subsequently spotted by the German supply ship to which Willi had been steering them. Before a launch can pick them up, both are sunk by an Allied warship. A frightened young German seaman is pulled aboard the lifeboat and the passengers argue about keeping him or throwing him overboard to drown. The rescued seaman brandishes a gun and after being disarmed asks, “Aren’t you going to kill me?”. Kovac repeats, “What are you going do with people like that?”
