La doublure
Pierre Levasseur is a wealthy married Parisian executive involved in an affair with top model Elena Simonsen. When a paparazzo catches the two of them departing their secret hideaway and their photograph is published on the front page of the local newspaper, Pierre's wife Christine confronts him. He claims he has no idea who the woman is, and that she must have been a companion of the man seen walking beside them. Fully aware of Pierre's difficult situation, Elena gives him an ultimatum: he must choose between her and his wife. Because Christine is the majority shareholder of his business, Pierre is in danger of losing his fortune if he divorces her. His lawyer Maître Foix advises him the only way to resolve the issue is to find the anonymous man in the photo and have him pose as Elena's lover.
The anonymous man is the hapless François Pignon, a parking valet who is in love with bookstore owner Émilie. Deep in debt and worried about her business, she has turned down his marriage proposal because she believes she has too much on her plate, and thinks of him as a brother. Meanwhile, Maître Foix locates François and offers him money to let Elena move in with him and pretend they are a couple. François agrees and asks for 32,450 euros: the exact amount of money that will pay off Émilie's debts. Meanwhile, Elena demands 20 million euros to participate in the sham relationship, a sum she keeps as a deposit that she will return to Pierre when he leaves his wife. Dislodging his friend and roommate Richard, Elena moves in with François, who is overwhelmed by the situation, but the two quickly become friends.
Christine is not fooled and plays the situation for all it is worth, making her husband jealous of François and Elena's living situation. Émilie, too, is confused and upset to see François and Elena together. Eventually, Elena explains the situation to Émilie, who is grateful for the funding François requested for her, and she acquires a newfound respect for him and eventually accepts François' proposal.
In the meantime, Christine secretly tape records Pierre saying he has no intention of leaving her for Elena and offering to take his wife on a second honeymoon. When she sends the tape to Elena, Elena decides to leave Pierre. She notifies Pierre of her leaving by sending François to meet him in her car at a secret rendezvous point. François conveys the news to Pierre who angrily responds that he has voided the 20 million euro transfer. François then tells Pierre that Elena anticipated this of him and indicates that she never wanted the money implying that Elena leaves the relationship with a clean split. François then walks away from the limo as a cross-dressing prostitute approaches Pierre and the two are photographed by a paparazzo.
