In a post-war Rome of 1946, a cat burglar inadvertently saves the life of a would-be suicide man who has returned from the war to find that he has been betrayed by his fiancée. From that moment the thief takes the ex-soldier under his wing. They leave the house together for a night full of misadventures. In the streets of Rome they meet a struggling typist who can’t pay her rent and opts for streetwalking; and a wandering amnesiac who lost his memory and keeps asking everyone “Do you recognize me?”.
