Five Deadly Venoms

A dying martial arts teacher instructs his sixth and final pupil to check on the activities of his five former pupils, each of whom he had taught a unique and lethal style of kung fu: the Centipede, the Snake, the Scorpion, the Lizard and the Toad (hence the film's title). This pupil, who knows a little of each one of the five styles, must team up with one of the other good pupils to destroy the evil ones, if there are any at all. Greed and treachery ensue as the pupil soon discovers that some of the pupils are indeed evil, but which one can he trust enough to team up with, if any?
