Dragon Fist

A young fighter (Chan) watches in horror as his master is beaten by a man. Eventually the wounds lead to the master's death. The young fighter (Chan) therefore trains very hard until his skills are good enough to combat the killer but the young fighter comes to know that the killer has since crippled himself after his wife's related suicide. The young fighter is therefore trapped in a predicament where he cannot take revenge without appearing to be a coward.
