Jackie Chan masters comedic Kung Fu as Wong Fei-Hung.
The plot centers on a young and mischievous Wong Fei-hung (sometimes dubbed as "Freddie Wong"). Wong runs into a series of troubles. Firstly, he teaches an overbearing assistant martial arts teacher a lesson. Next, he makes advances on a woman to impress his friends, and is soundly thrashed by her older female guardian as a result; his shame is compounded when these two are later revealed to be his visiting aunt and cousin, whom he had not met before. Lastly, he beats up a hooligan who is the son of an influential man in town. His father decides to punish him for his behavior by making him train harder in martial arts.
In turbulent China before World War I, the collapse of the Manchu Dynasty fuels violent uprisings and political chaos - the perfect setting for a grand-scale smuggling ring led by an unscrupulous British consul. When the ring plots to steal China's crown jewels, only one man - legendary 'Drunken Fist' master Huang Fei-hung (Chan) - possesses the courage and ferocity to stop the ruthless gang.
