Picked up by a beautiful motorist, jobless hitchhiker Pierre (Hossein) is subsequently romanced by the girl. Immediately thereafter, however, she dumps him, attempting to run him over as a final insult. Memorizing her license number, Pierre pursues the enigmatic motorist. Arriving at her home, Pierre is met by two young ladies (Marina Vlady and Odelle Versois), either one of whom might be the woman he's looking for.
