After avenging the death of his brother, Chen Shen (Bruce Li) returns home from Shanghai. He tells his mother (who went blind from crying over her sons death) that he will no longer fight. However, being a movie with the words fist and fury in the title, Chen doesnt keep his promise for very long. Japanese occupiers who are aware of Chens history terrorize his family by, among other things, vandalizing his mothers store and beating up his brother. Later, they frame Chen for a murder. After the Japanese boss arrives in town and causes a ruckus, Chen breaks out of jail for a final confrontation.
