Based on a novel by Emile Zola, the film stars Gerard Philipe as Octave, an opportunistic Parisian youth who hops from bed to bed -- and from bedmate to bedmate. Young or old, plain or beautiful, Octave loves and leaves 'em all. His romantic rovings come to a halt when he meets pragmatic businesswoman Mme. Hedouin (Danielle Darrieux). Apparently impervious to Octave's charms, Mme. Hedouin nonetheless marries the boy and transforms him into a useful (and least to her) member of society.
