A sixteen-year-old boy insinuates himself into the house of a fellow student from his literature class and writes about it in essays for his French teacher. Faced with this gifted and unusual pupil, the teacher rediscovers his enthusiasm for his work.

Prolific French filmmaker François Ozon (Swimming Pool, Frantz) crafts this creative thriller: a cat-and-mouse game between a teacher and his creative writing student, whose ever-elaborating story-within-a-story begins to entwine everyone around him. An inventive and entertaining literary comedy.
