Netflix Releases ‘El Monstruo de Florencia,’ a Four-Part Drama on Italy’s Unresolved Serial Murders

Sollima’s series frames the case through rival theories grounded in court files to expose decades of investigative gaps.

Overview

  • The miniseries debuts worldwide on Netflix on October 22, 2025, with all four episodes available at once.
  • Created by Leonardo Fasoli and Stefano Sollima and directed by Sollima, the production draws on judicial records and journalistic sources.
  • The story retraces eight double homicides of young couples near Florence from 1968 to 1985, long linked by a Beretta .22 and never conclusively solved.
  • Rather than naming a culprit, the series dramatizes competing theories such as the “pista sarda” and other lines that implicated multiple suspects over decades.
  • The Italian cast includes Marco Bullitta, Valentino Mannias and Francesca Olia, in a production by AlterEgo and The Apartment running about 217 minutes.
