15 January 1993. Cosa nostra 'superboss' Salvatore Riina has been arrested after 23 years, and receives a visit in prison from his childhood friend, Biagio Schiarò, triggering a flashback. In 1943, as a boy of 13 years, Riina is working in the fields around the town of Corleone when he finds a buried bomb. His father decides to take the bomb home, in order to extract the gunpowder from inside in order to sell it to hunters in order to supplement his very low farm labourer's income. The bomb explodes, killing Riina's father and younger brother, and leaving Salvatore as the head of the family to lead a life of misery. Tired of living in poverty, Totò, together with his friends Bernardo Provenzano (aka Binnu), Calogero Bagarella and Biagio Schirò, begins to work for Luciano Liggio, Picciotto of the boss Michele Navarra, who meanwhile orders the kidnapping and murder of Placido Rizzotto. Soon after, Totò gets into a murderous fight with 'Menico, the son of miller to whom Totò sells his grain, and ends up in prison; meanwhile Schiarò's change of heart takes him back to school. Six years later, Totò, an adult by now, is freed. Waiting outside the prison gates are Provenzano, Bagarella and a new member of the gang, Luciano Maino. Riina soon picks up where he left off in Liggio's gang: intent on more power and infamy, the gang murder the capo Michele Navarra and plan to expand towards Palermo. Schirò, meanwhile, has become a police officer and is working with Chief Inspector Angelo Mangano on Liggio and his gang. Totò meets the studious younger sister of Calogero Bargarella, Ninetta, and falls in love. It soon emerges that Ninetta is a close friend of Teresa, who in turn is dating Biagio Schirò.
