In order to get to know his two French collaborators better, Henry Wydmark, director of a large American company, invites them to spend a weekend in the Alps. They consider this trip to be part of their job. But as the wife of one and the husband of the other are not free, they do not hesitate to leave their "heart under the mat" and hire one a husband of convenience and the other a wife fictitious. This misunderstanding will trigger a cascade of disasters.
En un barrio moderno y anódino, donde todo está excesivamente organizado, viven monsieur Arpel, su esposa y su hijo Gérard, que se aburre soberanamente. La llegada de su tío, monsieur Hulot, un personaje soñador y lleno de fantasía, alterará ese mundo tan aséptico, sobre todo porque no tarda en convertirse en el mejor amigo de su sobrino.
