In this old martial arts movie, Chan Hui Lau plays Chang, who owns a winery and is a master of Drunken Boxing, a deadly form of kung fu that requires its practitioner to be drunk. When he catches Li Yi Min and Jack Long stealing grapes from his vineyards, his quiet life is turned upside down. He puts them to work for him. Over time, he shows them how to box while drunk. When the two boys fight with some rough locals, they make Chang's enemy Yeh Hu (Lung Fei) angry.
