While aboard a transatlantic passenger ship, a German woman, Liza, notices someone who looks like Marta, a former inmate at Auschwitz, where Liza used to be a guard.

The last film of Andrzej Munk, who died in a crash during filming. A German woman on a ship returning to Europe notices the face of another woman which brings recollections from the past. She tells her husband that she was an overseer at Auschwitz during the war, but she actually saved a woman's life. Her vision is shown and then the actual events.—Polish Cinema Database <http://info.fuw.edu.pl/Filmy/>
