Despite its stand-alone title, this mixture of martial arts and exploitation is a semi-sequel to Shaw Brothers's Flying Guillotine series. This time, the focus is Rong Qui-yan (Chen Ping), a kung fu student turned dutiful wife whose life falls apart when her husband is murdered by a squad of government operatives led by the duplicitous Jin Gang-Feng (Lo Lieh). Qui-yan is forced to go into hiding as she plots her revenge and finds allies in fellow fugitive Ma Seng (Tsui Siu Keung) and ex-lover Wang-jun (Yueh Hua). Meanwhile, Jin Gang-Feng sends out an array of killers to track them down. Complicating things further is the fact that Qui-yan is pregnant and struggling to keep her unborn child safe while fighting her way to safety.
A dying teacher instructs his final student to check on the activities of five former pupils, each of whom he taught a unique and special style of kung-fu: Centipede, Snake, Scorpion, Lizard, and Toad (hence the title). His final student, who knows a little of each style, must team up with one of the other good students to destroy the evil ones, if there are any. Greed and treachery ensue as the student discovers that some of the students are indeed evil, but which one can he trust enough to team up with? Written by Ken McCary kmccary@amaroq.ces.ncsu.edu
