Plot

Little Jean-Claude was adopted by former singer Jacques Duffot and his wife Anne-Marie. The child's mother, Simone, is determined to take him back, happily advised by the director of a private agency. They persuade Anne-Marie that Jacques is the legitimate father. Distraught, the young woman leaves home. Jacques resumes his singing career, but Jean-Claude refuses to accept the separation and fries him to death. The couple reconcile at his bedside, while Simone tiptoes away.
