Dick Ekland (Christian Bell Christian Bale) was once a famous fighter, but he was depressed because of his drug addiction. HBO came to make his documentary and faithfully recorded his life. Dick places his boxing dream on his brother Mickey Ward (Mark Wahlberg Mark Wahlberg) and is willing to practice, while his mother Alice (Melissa Leo Melissa Leo) acts as an agent. Mickey used to be a Golden Glove player, but now he is just a construction worker, training hard to make a comeback. One day, Mickey and Charlene (Amy Adams Amy Adams) fall in love at first sight. Brokered by ESPN, Mickey suffered a crushing defeat against a player who was 20 pounds heavier than him. In grief and helplessness, it was Charlene who comforted him, and the two began to associate. But the family is extremely opposed. At this time, Dick was arrested and impersonated as a policeman in order to raise money for Mickey, which also affected Mickey. From then on, the brothers turned against each other, the family supported Dick and Charlene supported her brother. The situation was deadlocked until Mickey returned to the game. Christian Bell and Melissa Leo won separately for this film.
