December 1969, in Corleone Teresa, with Biagio, gives birth to little Antonio. During the same hours, in Palermo, in secret from the other mafia family heads, Totò Riina, Binnu Provenzano and Calogero Bagarella, disguised as policemen burst into the Moncada construction company with the intention of killing the boss Michele Cavataio. They succeed but Calogero, in turn, is killed. Binnu and Totò secretly bury their friend in Corleone also so as to avoid leaving their calling card on the umpteenth massacre. The young head of police Boris Giuliano investigates with Mangano and senses that a body is missing from the crime scene. It is Biagio, who in the meantime has accepted a transfer to Palermo, who realizes that it is Bagarella but it is impossible to prove it: the Corleonesi have killed the witnesses. Riina in the meantime, like the Palermo bosses, wants a part of the big business run by Vito Ciancimino, the Corleonese who has become mayor of Palermo, but needs greater funds. Therefore, Provenzano and he, without Liggio’s approval, kidnap the thirteen year-old Antonino Caruso, whose family is strongly linked to the member of parliament Bernardo Mattarella. Despite the freeing of the adolescent, the mafia bosses fear the heavy reprisals of the Public Prosecutor against the families, thus Riina, without any hesitation, arranges for the Public Prosecutor to be killed and, with the support of Badalamenti and Buscetta, joins the regional mafia “Commission” while Liggio, who starts to be a burden to Riina, thanks to a tip-off, is soon arrested. Ninetta in turn is called before the court, the judges want to send her to the border in North Italy accused of aiding and abetting the Corleonesi mafia band. While the young woman is questioned, Teresa and little Antonio are intimidated by Riina’s men. Ninetta is finally released to her home town and condemned to special surveillance but in concurrence with her marriage – celebrated secretly - to Totò she disappears and also becomes a fugitive. Biagio, with his friend and colleague Silvio, try in every way to hunt down Riina who, seeing danger draw near, decides to go on the counterattack. He kills Silvio and beats up Biagio, threatening him to stay away from him. Riina in fact is invincible and continues to extend his power in Sicily. In order to achieve his aims, in 1978 he arranges for Peppe Di Cristina from Caltanissetta and Pippo Calderone from Catania - another two bosses and his bitter opponents - to be killed.
