Tell No One

Margot (Marie-Josée Croze) was murdered by a serial killer eight years ago, and her husband, Alexandre (François Cluzet), continues to mourn her death. One day, the police discover two dead bodies near Alexandre's home, along with a cache of evidence implicating him in the crime. On the same day, Alexandre receives an email with a video showing his wife alive and well, along with a simple message: "Tell no one." With the police breathing down his neck, Alexandre goes on the run.
