When hot-blooded Kuo Chung indulges his penchant for fighting once too often, the enigmatic Snake Fist Master saves him, then takes him under his wing and trains him in the devastating snake fist style of kung fu. But as Chung completes his training, he learns that his mentor has been using him to carry out an old and deadly grudge against Chung's own family. Wilson Tong directs this lively kung fu flick.
