A lacerating biopic of Jake LaMotta, the middleweight boxing champion who was known as “The Bronx Bull” and “The Raging Bull” during his brief reign. LaMotta had early lessons in life: to steal and to fight. He channelled his tough childhood into the ring, where his aggression became a way of combating deep-seated anxieties and emotional fears. This determination and rage turned him from a young hoodlum into a champion. But his drive for the title, his brutality outside of the ring and his almost-psychotic sexual jealousy will destroy his marriage, his deepest friendships and the career he fought to build.
