An aging dentist looks for a little liveliness by abandoning his wife in favor of a younger woman. When he learns that his mistress also has another younger lover, he gets jealous, but tries not to make an issue of it. In the end, he dumps her and returns to his wife, who is not about to stand for his middle-aged immaturity. She leaves him.
Paul (Teenager)
Deserted by his father, and dislocated by the Second World War, Paul is a boy who wants affection and attention and cannot find it at home. For a while, he becomes the pet of some German soldiers, running errands for them. Later, he helps the Resistance, and when the Americans come to stay, he is really in his element with them.
Paul has been imprisoned for ten years for passing counterfeit money. He feels victimized enough, both for the prison time and for the crime which led to it; he committed the crime to give his wife the nice things she asked him for. When he discovers that she has remarried a quite wealthy man, he is outraged. However, his ire is not due to her disloyalty to him; he loved their only son to distraction, and now the boy has no knowledge or memory of him.
Roberto (uncredited)
Roger Santet is a convicted murderer sprung from prison by the Sicilian clan headed by the aging Vittorio Manalese. They conspire to steal a large cache of jewels from an exhibit in Rome. As they are preparing for the heist, the mobster's American friend Tony Nicosia suggests that a better way to get the rocks would be to hijack the transport plane while it is en route to New York. The dogged inspector Le Goff is using all the available resources to thwart their plans. Though the heist itself is successful, Santet finds himself trapped by the mob because of his fling with Manalese's daughter-in-law.
