During the Ching Dynasty period, the Wu Tang must fight against the Shaolin. To create more chaos, the Venoms enter the picture for more intense fighting action. This 1980 classic was produced by the Shaw Brothers.
During the Ching Dynasty, there were two renowned martial arts clans, Shaolin and Wutang. Shaolin, being anti-Ching, was in constant conflict with the hostile Wutang which supported Ching government.
Tung Chien-chin (Lo Meng), a Manchu youth, is sent to Guangzhou to contact fellow Shaolin member, a skilled martial artist, Wu Hui-kan (Chiang Sheng) on an anti-Ching mission. Upon arriving, he is confronted by Wutang member Li De-chung (Yu Tai-ping), and in the ensuing fight, Li's flying knives wound him.
Tung recovers from his wound under the care of Chin Pi-erh (Yang Tsing-tsing) and her brother Chin Tai-lai (Sun Chien) and learns a defense technique against Li's flying knives. One day, Tung and Wu accidentally run into each other. Knowing that Li has spotted them, they plot to get rid of him. After killing Li they are both challenged by Li's brother Li Pa-shan (Wang Li) and his men, but after a fierce fight, the two champions of Shaolin defeat them.
Tung marries Chin Pi-erh, and Li Pa-shan's men disguise themselves as wedding-guests in order to kill both brother and sister and kidnap Tung out of revenge. Wu Hui-kan is elsewhere drunk, and escapes danger. Wutang's Wei Hsing-hung who secretly sympathises with Shaolin sets Tung free.
An expert Wutang martial artist plots to establish a close friendship with Tung and Wu in order to kill them. Wei, who then assists them to defeat Wutang in a fierce battle, warns them of his intentions.
