The story of the 1986-87 "Maxi-trial" against Cosa Nostra in Palermo, Italy. Instructed by the Anti-Mafia pool, led by Giovanni Falcone and Paolo Borsellino, the story of this historical process and of its exceptional numbers is recounted through the real images from court audiences enriched by reconstructions with fictional scenes.

How, from 1974 to 1993, Totò Riina (1930-2017), supreme boss of the Corleone family, ruled by blood and terror over the Sicilian Mafia. An implacable account, based on the testimony of his men and those who fought against them.
