The Mischief Makers (1957)

Les Mistons

A group of young boys have a collective crush on Bernadette. As a result of this, they have an unreasoning jealousy of Gérard, and do everything they can to disrupt their relationship. When Gérard catches one of the young boys spying on them, he thrashes him severely. In retaliation, the children try to inspire Bernadette to doubt Gérard’s love.
