Between January 1996 and July 1997, five women went missing in and around the city of Mons in Belgium. Their disappearances weren’t linked until gruesome discoveries were made across the city. Fifteen trash bags containing thirty-seven body parts were found at strategic dump sites seemingly designed to taunt authorities and spark fear in the public. These women fell victim to a sadistic serial killer. His identity remains unknown, but his name still sparks fear… The Butcher of Mons. In this new season of Le Monstre, Host Matt Graves and a team of investigators and journalists reinvestigate this terrifying case, unearthing new evidence, new witnesses, and new suspects.

Season 1 of Le Monstre covers The Dutroux Affair. Serial killer Marc Dutroux and his accomplices terrorized the country of Belgium. These unspeakable crimes and the incompetence or unwillingness of law enforcement agencies to stop them brought the entire country of Belgium to the brink of revolution.
