Everyone Dies Alone (1962)

In wartime Berlin, a factory foreman, Otto Quangel and his wife, Anna learn that their only son, Paul, has been killed in action in France. In their grief, the couple decide to take action against the Nazi regime. They create their own form of resistance, writing postcards urging people to resist Hitler and the Nazis and quietly distributing the postcards around Berlin. Various people enter the picture, showing the fear and distrust of the times. People, such as the actor Harteisen, find the cards and race to turn them in, lest they be found with them and come under suspicion. The police and the Gestapo are baffled for over a year, but finally find the source of the cards. The Volksgerichtshof sentences the Quangels to death.
