His mother dies shortly after his release, and despite the objections of his only friend, Jacques, and his mother's neighbor Jeanne, Michel teams up with a couple of petty thieves in order to improve his craft. With a police inspector keeping an eye on him, Michel also tries to get a straight job, but the temptation to steal is hard to resist.
