This is Sun Chung's very first film for the Shaw Brothers, making it especially interesting and important. He hit the ground running with this action-filled tale of a "Devil Girl" who is setting one clan against another to get her hands on two amazing mirrors with supernatural powers. Only a noble swordsman (played by Liu Tan) and beautiful swordswoman (played by The Thundering Sword star Shu Pei-pei) can stop her.
