The Traitor. Based on the true story of the Cosa Nostra in the early 1980’s, the film begins as an all-out war rages between Sicilian mafia bosses over the heroin trade. Tommaso Buscetta (Favino), a made man, flees to hide out in Brazil. Back home, scores are being settled and Buscetta watches from afar as his sons and brother are killed in Palermo, knowing he may be next. Arrested and extradited to Italy by the Brazilian police, Buscetta makes a decision that will change everything for the Mafia: he decides to meet with Judge Giovanni Falcone and betray the eternal vow he made to the Cosa Nostra.
