A rake and a noblewoman play a game of sexual chicken in Il ne faut jurer... de rein! (2005). In 1830s Paris, Valentin (Jean Dujardin) is a notorious womanizer more concerned with drinking and gambling than his gentlemanly duty. So when his uncle Van Buck (Gérard Jugnot) arranges a marriage for Valentin to the beautiful-but-impoverished baroness Cecile (Mélanie Doutey), he sets out to seduce her and prove that she's no better than the rest. But Cecile turns out to be more clever than Valentin had predicted, and soon the line between predator and prey has become hopelessly blurred. Another thing that's unclear is what's underneath Mélanie's dress, because despite some killer corseted cleavage the best we get is some stiff nippage underneath a sheer chemise.
