"The Thundering Sword can shatter world's other two precious swords. When the sword appears it could cause great disasters which would cease only when the earth cracks."
Yu Chien Wan (Chang Yi) and Chiang Kwun Yuan (Lo Lieh), two heroes from Baiyun Temple, were sent by their master to find the Thundering Sword. The master wanted to destroy the sword so the world would be peaceful.
|Chen Pei-pei as So Jiau-jiau|
Jiau-jiau killed 32 people in Yue Security Escort because they had failed the task, but because she disguised himself as a man, the only surviving victim pointed Yu Chien Wan as the culprit. Yu Chien Wan became a wanted man and when Jiau-jiau confessed, no one believed her.
Yu Chien Wan met So Jiau-jiau and they fell in love with each other. Jiau-jiau even gave him the Thundering Sword, although it was later seized by a skilled monk.
Things didn't go well for Yu Chien Wan and So Jiau-jiau. First because of the matter of Yue Security Escort and because Jiau-jiau had wounded Chiang. From this point the pace became slow and the story teary like soap operas.
