Everyone abuses and humiliates a downtrodden orphan (Chan) until he befriends an old man, who turns out to be the last master of the “snake fist” fighting style. Jackie becomes the old man’s student and finds himself in battle with the master of the “eagle’s claw” style, who has vowed to destroy the snake fist clan.

Jackie Chan stars as Wong Fei-Hung, whose mischievous antics land him in hot water. Having tolerated enough of his son’s mishaps, Fei-Hung’s dad enlists his sadistic uncle, who specializes in drunken-style kung fu, to teach the lad some discipline. This Hong Kong martial-arts comedy helped establish the slapstick fighting style that would become Chan’s trademark.
