Veteran star Claude Brasseur plays the cantankerous Henri of the title in this riotous comedy of bad manners and good intentions. Bitterly opposed to the relationship between his son Paul and the flighty Valřie, Henri strikes upon a devious plan. He offers free board to attractive student Constance, who, desperate to make her own way, agrees to use her charms to drive the couple apart. What ensues is classic farce material with a whirlwind of uproarious misunderstandings and awkward situations. Yet despite the wry cynicism at the beginning, there is still a sweet and uplifting message at its core, follow your dreams and don't waste a minute.
