This gentle French comedy, takes an intellectualized look at the nature of a crush as it tells the tale of 20-year-old Claire, a young woman seemingly suffering a terminal case of ennui. She glumly goes through the minimal motions of living until she falls in love with handsome Gregoire, a highly intelligent philosophy student. He gives her an unusual translation of Le Journal d'un seducteur by Kierkegaard. This is no ordinary philosophical tome and anyone who opens it becomes strangely aroused and susceptible to love. Not only is Claire entranced by the book's magic, her psychoanalyst also finds himself ensnared. Meanwhile, mysterious Gregoire seems to hold the key to the mysterious book in his refrigerator, and if he doesn't, then the corpse therein just may.
