Tell No One

Eight years ago, Margot Beck (Marie-Josee Croze) was murdered by a serial killer. Though the killer has confessed to seven of these murders, he has always denied to be responsible for Margot's death. However, the specific mutilations found on her body seem to remove all doubts over his guilt. Today, Dr. Alexandre Beck (Francois Cluzet), her husband, is still deeply psychologically injured by the loss of Margot. He temporarily escapes his memories during the day by immersing himself completely in his work as a pediatrician. Outside of that, only the friendship he has formed with Helene Perkins (Dame Kristin Scott Thomas) saves him from total isolation from the rest of the world. But when two new bodies are uncovered near where Margot's body was discovered, Margot's case is re-opened. At the same time, Alexandre receives a strange e-mail with a link to a video surveillance webcam and a time at which to watch it.
