Brigitte Bardot plays Sophie, a young model who discovers her boyfriend is thinking of leaving her for another woman.

Sophie is not content with the status quo in her relationship with high-flying reporter boyfriend Philippe (Jacques Riberolles), but she is even less impressed when a wealthy American girl, Barbara (Josephine James), threatens to steal him from her.

She enlists her doctor friend Alain (Michel Subor) to aid her in making him jealous.

Sophie and Alain travel from Paris to the ski resorts of Italy to chase Philippe and Barbara, treating us to marvelous French comedy in the mischief that ensues.

Michel Subor was cast as Bardot's fraught suitor, in a role that made him famous.
