During World War II, a diverse group of people in war-ravaged London books passage for the United States, but Austrian pianist-turned-soldier in the Résistance Henry Bergner (Paul Henreid) is unable to join them for want of an exit permit. Searching the streets for him during a German airstrike, his wife Ann (Eleanor Parker) witnesses an aerial bomb obliterate a car full of passengers on their way to the docks. She returns to their apartment to find that Henry has turned on the gas to commit suicide. Despite his attempt to dissuade her, she joins him.
