An investigation exposing how Italy's most ruthless organised crime syndicate has taken over one of the country's most beautiful cities, killing its citizens and poisoning its water, making massive amounts of money and effectively operating an alternative government. Italians are no strangers to organised crime and violence. Each region of Italy has spawned its own version of the Mafia. In Sicily, it is the Cosa Nostra. In Calabria, it is the Ndrangheta. The Camorra is the Naples mafia. Over the past three decades it has been responsible for the death of 3,000 people. Anyone who opposes the Camorra's rule becomes a target. Few are brave enough to resist its demands. Despite suffering setbacks at the hands of a few committed investigators, it remains as strong as ever. The Camorra is into drug trafficking, racketeering, business, politics and even the garbage disposal industry. Naples' recent waste crisis was in part blamed on the crime syndicate. Its grip on the city is far reaching. Talking to Camorra insiders who have never spoken to the media before, and drawing on interviews with Camorra victims who are fighting back, reporter Mark Franchetti investigates Italy's most brutal crime gangs and tries to understand how they have survived so long in a country at the heart of Europe and asks what it will take to defeat them.
