The much-pampered, oedipally-loved son of a neurotic french mother, disappears without a trace (almost) while running a routine errand. Years later, a street-hustler teen, claiming to be the long-lost boy, is brought to live with the family, reuniting the mother and the father but alienating the older sister who remains skeptical of the youth's identity. Not entirely flawless as evidence of the lad's true fate are dropped like Hiroshima bombs upon the viewer. Perhaps if a certain Australian singer/actress had played the mother this film could be retitled "Olivier, Olivier Newton-John".
