Adapted from Jin Yong's famous novel, Shih Chung Yu (Phillip Kwok) acquires an edict by chance, prompting swordsman Shih Yen Ko (Wang Li) to teach him a fatal type of kung fu with the intention of killing him. However, Chung Yu does not die and is mistaken as the Chief of the Chang Lo clan, Shih Yen Ko (Wang Li). He then meets Chung Yu's fiance Ting Tang and falls in love with her. On the basis of righteousness, Chung Yu agrees to die in the place of Yen Ko. Eventually, Chung Yu's true identity is discovered and traced back to his abduction as a baby.
