Eight years ago, Margot Beck was murdered by a serial killer. Though the killer has confessed to eight 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, Alexandre Beck, 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 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 reopened.
