In this film that sends up the foibles of filmmaking, a standard crew of actors, stage-hands, director, writers, producers, and others are gathered for the filming of a 45-second automobile commercial. Each role embodies an archetype (the harried director who has a deadline to meet, the Scrooge production manager who has a budget to meet, and the writers who are above these mundane concerns), and these personalities drive the working actors over the edge until they decide to lock them up and do their own thing -- happiness can be just around the corner if you are in the driver's seat. Hopefully, the actors will be able to bow out before the police catch on to the situation.

Julien and Emma are brother and sister, living in rural France with their father, who writes children's books. Julien is a gifted pianist but the loss of his mother has sucked the joie de vivre out of him; his best friend Alice knows it although their platonic relationship is more about him supporting her in bad relationship choices than anything else. When he sees a beautiful woman called Olga in a bookstore, Julien is smitten and sets about to set up someway of impressing her and winning her affection.
