The assistant (2015)

With his wife in labor, father-to-be Thomas (Malik Zidi) speeds to the hospital, and in the process, accidentally kills a young man on the road. That death sets into motion events that will change everyone’s lives forever, including the young man’s mother Marie-France (Nathalie Baye), who cannot recover from the trauma. Nine years later, Marie-France takes a job as Thomas’s secretary without him knowing about her connection to his past. As Marie-France’s maternal rage reaches tragic proportions, she insinuates herself into his life, his work and his family in this classic thriller à la Hitchcock.
