The Monster of Florence (Il Mostro) Plot
The Monster of Florence follows the true story of a serial killer who terrorized couples across the Tuscan countryside for nearly two decades. It begins in 1968, when a double murder shakes a small town and exposes deep social divisions. Years later, investigators realize the same weapon was used in a new string of killings between 1981 and 1985, leading them to suspect a single perpetrator behind all the crimes. The series examines multiple suspects — from Stefano Mele, the first man convicted, to the Vinci brothers, whose violent reputations drew police attention. As the story unfolds, it becomes clear that obsession and corruption within the system caused as much damage as the killer himself. Through evocative cinematography and emotional depth, the show exposes the lasting trauma of a nation still haunted by the question: Who was the real monster?
