Based on a True Story
Directed by Roman Polanski
Produced by WY Productions, R.P. Productions
A psychological thriller about creative exhaustion and female intimacy that grows increasingly ambiguous and unsettling as a mysterious woman insinuates herself into a novelist's life.
Delphine is the author of an autobiographical novel that has become a bestseller. Exhausted by the promotional tour, just when she feels out of place, paralyzed by the idea of having to start writing again, she meets Elle, a young, attractive, intelligent, intuitive woman who seems to understand her better than anyone.
