Now that the world conflict is over, five inseparable wartime buddies swear eternal friendship now to each other. But there’s many a slip ‘twixt the cup and the lip. Jean becomes a postman, Marcel a boxer, Roger an actor, AndrĂ© a student and Philippe remains what he has always been, a young man of good social standing. Roger, who can’t find any role, is introduced through his singer sister ValĂ©rie, to FrĂ©do, a shady nightclub owner.Roger soon becomes one of FrĂ©do’s henchmen. To make matters worse, he swipes Jean’s fiancĂ©e, Simone. Marcel, who loses fight after fight, ends up joining Fredo’s gang as well. AndrĂ©, who wanted to redeem the faults of his father during the Occupation, gets killed in the Indochina war. Marcel is shot down while taking part in a robbery. In her turn, ValĂ©rie is bumped off by an accomplice of Fredo and Roger is sent to jail.
