Another gripping episode of TV’s most dangerous documentary series focuses on the cold-hearted killer, Vita "Don Vito" Genovese. Born near Naples, Italy, Genovese moved back and forth between Italy and the US throughout an incredibly wide-ranging career. At one point he was even employed by the US military after the Allied invasion of Italy in World War Two! Don Vito did more than anyone to take the Mafia into the world of drugs, yet ultimately, he would be responsible for an error so huge that it would at last bring the wrath of the FBI down on organised crime.
