This slow Italian drama tells the true story of Mafia boss Tommaso Buscetta, who became the highest-profile Mafia informant at the time of his arrest in the 1980s.
Tommaso, while supervising a criminal network in Sicily, moved to Rio de Janeiro in Brazil to attempt a more legal and quieter life. His role catches up with him and he is quickly arrested.
As a biopic, it rarely depicts violence or glorifies organized crime. Instead, it attempts to document the life of a Mafia boss more realistically: a life of always looking over one's shoulder and of constant loss. Eventually, the movie focuses on what it would take for a man like Tommaso to flip, and what that would cost him.
The Mafia topic might feel overdone, but watching this, it's startling to realize how few thorough character studies have come out in film.
