A group of drifting youngsters train to commit petty thefts. A certain André puts them on the trail of a real hold-up. They might carry it out if a suicide attempt didn't stop them. A young woman throws herself into the river. They save her, comfort her, learn that she's pregnant. They surround her with their friendship. When André reappears and seizes Lucienne to throw her on the pavement, everyone unites to save her, and the kind-hearted Maurice offers to be the baby's loving father.
