A seemingly ordinary day in the life of Quentin, a Parisian film-lover. After going to the cinema twice, he runs into a former college friend, listens to a girls' conversation in a bar, then goes and meet his best friend, has a beer, and ends up spending the evening in the Parc Montsouris, where he meets Lise.

故事围绕一对年近五十的姐弟展开——爱丽丝是演员，路易斯是教师和诗人。他们不再互相交谈，二十多年来一直在躲避对方，但父母的去世将迫使他们走上歧途。
