Théo, a frustrated writer of erotic magazines, lives in the studio of his sister Cléo, who photographs nudes. Both go through a difficult period and blame each other for lack of inspiration. An editor, a friend of Théo, hires Cléo's works and so three girls appear to be photographed. Once introduced to the writer, the latter begins to nurture sympathy for the girls and, in this way, begins to create erotic tales based on her testimonies, muses that again inspire him in his creativity.
