This classic martial arts movie stars Chan Hui Lau as Chang, the proprietor of a vineyard and a master of Drunken Boxing. Drunken Boxing is a lethal kung fu technique that, as the name suggests, requires its practitioner to be inebriated. Chan Hui Lau plays Chang. His life was quite serene until he caught two youths (Li Yi Min and Jack Long) stealing grapes from his vineyards and forced them to work for him. This shattered the relative tranquility of his existence. Over the course of time, he educates them in the ways of the Drunken Boxing style. When the two lads get into a battle with some local toughs, they attract the anger of Yeh Hu, who is Chang's adversary. Lung Fei plays the role of Yeh Hu.
