This is the true story of Vito Ciancimino - DON VITO da Corleone, the 'Mayor of the Corleones' - who spent forty years in the grip of death, mafia, politics, business deals and the secret service. DON VITO recounts years of clandestine and previously censored contacts between politicians and the mafia - between the Italian State and the Cosa Nostra. The key witness is Massimo, the penultimate and hitherto closest of DON VITO's five children, who has given his personal testament for the first time.
