After his critically-acclaimed directorial debut, Mon Idole (Whatever You Say), French actor Guillaume Canet now brings us Tell No One, based on American writer Harlan Coben's bestselling thriller. Pediatric Alex, devastated since his wife Margot was savagely murdered in the early days of their marriage eight years before, receives an anonymous email. When he clicks on the link indicated, he sees a woman's face standing in a crowd and being filmed in real time. Margot's face... Is she still alive? And why does she instruct him to tell no one? So many questions that our hero does not have time to consider: he barely even has time to raise the lid of this Pandora's Box before the police reopen the case. And, eight years down the line, the cops are determined that he will take the rap for murder.
