Freddy Wong (
Jackie Chan) in
Drunken Master,
Beggar So / Sam Seed returns to find that his wife has adopted a son named Foggy. Sam takes a disliking to the boy and tortures him mentally and physically. Devastated, the boy runs away and takes a job at an inn, where he meets Rubber Legs and his student. He overhears that they are looking for Beggar So and want to kill him, making Rubber Legs' Northern 'Drunk Mantis' Boxing supreme. However, Foggy returns home to warn Beggar So, who comes to the inn to meet Rubber Legs in a drinking feast. During the fight, Rubber Legs brings out his drunk mantis fist he combined with his Northern style against which Beggar So turns out to know no defense in particular, to bear, beating him easily. Beggar So gets mortally ill and sends Foggy to a sickness teacher for herbs to cure him, and the doctor teaches him a dreaded style called 'Sickness Boxing'. Now, armed with this sick form of fighting, Foggy is ready for Drunk Mantis. In the end, Foggy goes berserk and kills Rubber Legs. Unable to escape from his trance, he sees Rubber Legs when he looks at Beggar So and attacks him. The film closes with a freeze frame as Foggy leaps after his adopted father as the sickness doctor watches on. ==Cast==
