Jake La Motta (RDN) is a head-strong pugilist. He listens to no one. Not even his brother Joey (JP), who is also his manager. He plays on the sympathy factor of the crowd. Looses the initial rounds and makes a comeback in the end, often losing games but winning the hearts of the crowds in the process.

He sees a beautiful girl, Vickie (CM), falls in love with her and marries her. He becomes absolutely possessive about her and does not trust anyone. And this results him in breaking relationship with everyone he knows. He goes on to win the world championship. 

But will he be able to defend it, will he be able to save his family life, will he be able to give up his self-centered ways?
