Yvan (writer/director Yvan Attal), a young sports writer, is married to Charlotte (Charlotte Gainsbourg), one of France's most famous actresses. They try to live a normal life, but her fame makes it difficult as autograph hunters interrupt their dinners, cops about to serve traffic summonses let them off with a warning and a smile when they recognise her, and impossible-to-get restaurant reservations magically appear when Charlotte makes the calls instead of Yvan.

All this threatens and challenges his male ego, but Yvan is able to take her stardom in his stride. Until, that is, a man at a bar asks him if he gets jealous watching his wife make love in the nude to another man on screen. It has never seriously worried him before, but the stranger has sown the first seed of doubt in his head...
