Directors Jean-Marc Barr and Pascal Arnold's sexually political drama Chacun Sa Nuit explores the carnal interdependencies among a host of characters who live in a town in provincial France. At the center of it all is Pierre (Arthur Dupont), a conceited and vain bisexual musician in his late teens who acts as a magnet, to varying degrees, for a whole array of characters -- from his sister, Lucie (Lizzie Brocheré), with whom he has a heated incestuous relationship, to a city councilor with whom he participates in gay orgies. When Pierre turns up dead, Lucie investigates the reasons for his demise and charts the network of sadomasochistic relationships that crisscross the town. Arnold wrote the screenplay, based on an actual series of events; the picture co-stars Pierre Perrier, Nicolas Nollet, and Guillaume Baché.
