In Paris, an anorexic artiste called Camille (Tautou) works as a cleaning lady in anonymous office buildings to make ends meet. She lives in an unheated garret in an enormous 18th century apartment building that also houses the spacious apartment of the blueblooded gentleman Philibert (Laurent Stocker). He shares the baroquely decorated rooms of the house - that actually belonged to his recently deceased grandmother - with his rather improbable and moody housemate Franck (Guilaume Canet), a bike-riding chef who visits his grandmother Paulette (Françoise Bertin) every Monday and pretty much works all other days. No points for guessing who is the sidekick and who is the true love interest for Camille – almost against his will at first. (Extra points, however, for those who noted the nice symmetry in the importance of the grandmothers.)
