A clan sends out two of their members (Lo Lieh and Chang Yi) to retrieve a powerful sword to prevent its misuse. Along the way they encounter a skilled swords-woman who is also after the sword (Cheng Pei-pei). A complex love tragedy develops when she falls in love with one of the men and thoughtlessly wounds the other. Though the sword is found it becomes secondary to the love story and the guilt of the woman over her hasty and violent actions towards her lovers clan.
郑佩佩张翼真是赏心悦目的一对儿，侠情片典范。5549:神剑震江湖。绝对是倚天屠龙记的改编。
