Zhuo Yihang was raised by Taoist Ziyang of the Wudang Sect and groomed to become a young chivalrous swordsman. He is placed in command of a coalition army formed by the eight major orthodox martial arts sects, which aim to prevent an evil cult from infiltrating China. During a battle against the cult, Zhuo Yihang meets a young woman called Lian Nichang and falls in love with her. She is an orphan and was raised by wolves as an infant before being adopted by Ji Wushuang, the Siamese twins who lead the cult. After consummating their romance, Lian Nichang decides to leave the cult and follow Zhuo Yihang in pursuit of an ordinary life away from the jianghu (martial artists’ community).
Lian Nichang succeeds in leaving the cult after suffering great pains. Meanwhile, Zhuo Yihang returns to Wudang and is horrified to see that his fellows have been murdered. The coalition believes that Lian Nichang is responsible and attack her when she arrives to meet Zhuo Yihang. Zhuo Yihang is forced to turn against Lian Nichang. Devastated by her lover’s rejection, Lian morphs into a vicious white-haired killer and slays all the coalition members present. Suddenly, Ji Wushuang appears and reveals that he/she is actually the one who killed the Wudang members. Zhuo Yihang and Lian Nichang combine efforts to defeat and kill Ji Wushuang. However, even after the victory, Lian Nichang vows never to forgive Zhuo Yihang for betraying her and walks away while Zhuo looks on helplessly. In a brief epilogue set years later, Zhuo is alone in a remote mountain region guarding a rare flower that is said to bloom only once every several decades and has the ability to reverse the effects of ageing (turning white hair back to dark). Believing that it can cure the harm he has inflicted on Lian Nichang, he awaits for the return of his loved one and hopes that she will show up.
