French farce master Francis Veber (The Dinner Game) combines slapstick laughs with rapid-fire dialogue as he tells the tale of a Parisian valet unwittingly drawn into the affairs of a wealthy industrialist. François Pignon (Gad Elmaleh) is a simple valet employed by a posh Paris restaurant. Blissfully unaware of the paparazzi stalking powerful businessman Pierre Levasseur (Daniel Auteuil) and his stunning mistress, Elena (Alice Taglioni), the innocent passerby François wanders haphazardly into the frame. Realizing that the common man in the photograph may be Levasseur's only hope of avoiding a nasty divorce from his wife, Christine (Kristin Scott Thomas), Pierre's quick-thinking lawyer (Richard Berry) arranges for François to live with Elena in order to mislead the tabloids. Having just been dumped by childhood sweetheart Emilie (Virginie Ledoyen), François accepts the proposal, in the hopes he can win her back through jealousy. But Pierre's jealousy flares, Elena grows frustrated with her new digs, and Christine might know more than she's letting on.
