Leaud portrays a Parisian publisher of romance novels who hits on the gimmick of having his live-in girlfriend (carrot-top cutie Helene Lapiower) pose as author Rosine de Beaumont for book jacket and autograph signings. She's an immediate hit but rebels against being exploited, and throws Leaud out of their apartment. Complications occur when she meets a nerd (Rufus) claiming to be the book's author, leading to discovery of the real author (Thierry Fortineau), a bookseller who"s so happy to be in print at last that he's not to miffed at the deception. Climax shot at Charles de Gaulle Airport neatly weaves plot threads together for a blissfully happy ending.
