Set in Rome during the late 1970s, the series chronicles the rise and fall of the Banda della Magliana, a ruthless criminal organization that dominated the city's underworld for over a decade. Led by the charismatic and volatile 'Libanese', the gang begins as a small-time kidnapping operation but quickly evolves into a powerful syndicate that infiltrates the highest levels of Italian society, including the police, the secret services, and the Mafia. As the gang gains power, internal rivalries, paranoia, and the relentless pursuit by the principled Inspector Scialoja threaten to tear the organization apart. The series masterfully weaves historical events of the 'Years of Lead'—such as the kidnapping of Aldo Moro and the Bologna massacre—into the fictionalized narrative, painting a dark, gritty portrait of a city consumed by corruption, violence, and the pursuit of absolute control.
