On June 26, 2003, Michel Fourniret was arrested for attempted kidnapping of a minor. He risks, at best, only a few months in prison. Yet the police are convinced they are dealing with a serial killer. But they have no proof … Fourniret admits nothing, does not crack. One person, however, must know: his wife, Monique Olivier. What does she know? Is she a witness? Partner in crime ? But above all, how to get her to speak?
The countdown begins and begins a real psychological hunt to bring down one of the most famous and enigmatic serial killers in history.
At the casting, we will find Francois Xavier Demaison (Commissioner Yann Declerck), Melanie Bernier (Police Captain Margaux Nielsen), Isabelle Gelinas (Monique Fourniret), Philippe Torreton (Michel Fourniret), and Yves Renier (prosecutor Arnaud Costenoble).
