The movie started with a man who had a brain damage because of a boxing match. He told a man to get his wife, and she came to see him. There was a press conference where another man said that he wanted to set up a fight with another man, but then the man's wife said he was retired. It turns out the man and his wife lost money because of something they did, and they had to move to Philadelphia.
While there he met a young man who wanted to box, and he had him for dinner. The man's son was mad because he had to leave. He became his friend, and then he was sad. He won a bunch of boxing matches, and then the other man introduced him to a beautiful woman. Him and the woman and the man started to be against him. He had a nice car, and drove away while he tried to talk to him.
In conclusion they fought outside, and it showed that he was right all along. Then the man said he'd sue him, but he punched the man anyway. At the end him and his son went to the library.
