Robert (Malavoy) has divorced the dreadful Veronique (Thevenet) and struck up a friendship with Juliette (May). He admires the way her life seems so satisfied and orderly but Juliette decides she doesn't like this idea of herself and impulsively drops her swinish fiance Patrick (Penot) and pursues Robert instead. But Robert is only interested in friendship, leading to some very twisted revenge plots. Suspenseful look at what obsessions can drive people to do. Adapted from the novel by Patricia Highsmith. In French with English subtitles.
