Up-and-coming French movie idol Alain Delon is the philandering playboy Julien in this light-weight romantic comedy by Michel Boisrond. Julien is engaged to be married but that is no impediment to starting up a flirtation with Sabine (Mylene Demongeot), a married woman, or Agathe (Pascale Petit), her charming friend, or Helene (Jacqueline Sassard), a quiet and serious woman. When all three friends find out what is going on, they begin to plot a murderous revenge. Fortunately, mayhem is averted and Julien is properly repentant as the plot turns toward the home stretch.
