Russell (Christian Bale) and his younger brother Rodney (Casey Affleck) live in a poor and closed industrial town. The simple desire to leave here one day has become the only motivation to support the two brothers. They work hard every day to realize this wish. God is blind, and bad luck has fallen on the two brothers who are indifferent to the world. Because of an accident, Russell had to face a four-year prison. When the long four years finally came to an end, Russell, who returned to society, found that Rodney had already become a wisp of wronged soul. It turned out that after Russell was imprisoned, Rodney, who was alone, was tempted by a traitor and began to fight illegal boxing matches in the underground black market, which directly led to his death. Sadness and anger surged in his heart, and he decided to avenge Rodney.
