Italian crime drama centred on the life of Sicilian Mafia boss Tommaso Buscetta (Pierfrancesco Favino). The film follows Buscetta as he attempts to leave the Cosa Nostra and flees to Brazil. In retaliation, a number of his allies and family members are murdered in Sicily, and it's not long before Buscetta is extradited back to his home country, where he becomes an informant for anti-Mafia judge Giovanni Falcone (Fausto Russo Alesi).
