L'éducation amoureuse de Valentin

This sex comedy concerns the efforts of Julien to get his timid, "backward" 20-year-old son to take an interest in sex and get married. After a series of adventures with women (arranged by papa), Valentin finally gets married to a woman who appears to be as shy as he is. Things get complicated when his father begins an affair with her.
