Alex Ponttin, Michel Serrault, has endured two hard blows: the loss of his wife and the end of his career as a tweed tailor. In response, he conceives a sly and oddly hopeful way to stay connected to the world: he slips into people’s homes by posing as a relative or an official, then convinces his hosts to offer him a night’s shelter for free. What begins as a desperate ploy soon becomes a vehicle for mischief, irony, and a pointed social critique.
His first notable encounter is with the Dumont couple, Jean-Pierre Bisson and Maike Jansen. Over a tense lunch, a thief trails him, foreshadowing the way Alex will drift through other households and blur the lines between deception and generosity. The experience sets the tone for a film that plays with trust, intrusion, and the fragile boundaries of civility.
Alex then spends an evening in front of the television at Marie, Marie-Christine Barrault, mother of seven, before slipping away toward a new bed and a fresh audience of strangers. His path leads him to Caroline, a charming but shy lesbian described with warmth and wit, Claude Jade, and her lively lover Gloria, Corinne Le Poulain. The trio’s dynamic introduces a playful, human angle to the satire, contrasting everyday intimacy with the blunt judgments that society often imposes on such lives.
To protect her inheritance, Caroline—saddled by a cruel sister Catherine, Laurence Vincendon—claims to her aunt Amélie, Monique Darpy, that Gloria is her secretary and that Alex is her lover. The ruse requires a bold image: Alex must present himself nude in Caroline’s bed, a provocative statement meant to seal the inheritance and expose the fragility of moral posturing.
As the plan unfolds, the authorities close in, yet the investigation is hampered by stumbles and blunders that keep Alex out of custody. The police, represented by Inspecteur Bruneau, Jean-Claude Dreyfus, emerge as comically ill-equipped to pin him down, heightening the sense that the real power lies not with law enforcement but with the unpredictable, everyday figures who populate this world.
In true Jean-Pierre Mocky fashion, the film carries a sharp anti-establishment subtext. It skewers self-proclaimed moral authorities—the police, the clergy, and even the President of the Republic—while elevating the outsider. Alex Ponttin’s audacious freedom becomes a symbol of how a break from convention can illuminate the mediocrity and moral laxity that plague modern life. The narrative suggests that genuine integrity and a more humane society might originate from those who don’t fit neatly into established roles, and it does so with a satirical wit that invites both laughter and reflection.
Ultimately, Serrault’s performance anchors the film, presenting a bemused, impish figure who uses his unconventional liberty to nudge others toward better, kinder ways of living. The story blends humor with a wry diagnosis of contemporary life, offering a memorable portrait of an unconventional reformer who challenges the inertia of society while remaining, at heart, a deeply human outsider.
