Jules Duraton is the headmaster of Chatelbourg's high school. He is happily married, has a teenage daughter named Solange, and everything would be for the best of all possible worlds if he and his family were not the namesakes of the protagonists of a famous comic series broadcast every day on Radio Monde "La Famille Duraton".
Principal scenes from this kids' film, minus all shots featuring Sabu, were also used in the semi-adult film "Untamed Mistress", made and released by the same people in the same year.
A police detective finds himself entangled in the web of the underworld when he falls in love with a nightclub singer accused of murdering a crooked lawyer.
