Dian Tang Lang plot
"Mad, Bad and Insane"
Ah Chi is obsessed with martial arts and his kung fu antics regularly get him into trouble. His fight with a local bad boy, who turns out to be an accomplice of boss Hsia, forces his master to fire him from his gym. Chi, now masterless and working for a fishmonger, meets a cunning boy whose uncle Chow Tung is the master of the 'Insane Mantis Fist'. Though the old man refuses to teach him his techniques, Chi secretly learns as much as he can. After another battle with Hsia's henchman, the battered Chi is approved by Chow Tung. But when Hsia and his helpers kill the boy, Uncle Chow and the fishmonger, Chi is only driven by a kind of cannibalistic rage.
