A band of counterfeiters wants to make Hong Kong their new territory. The disgraced leader of the Special Squad will have to team-up with a group of Hong Kong police officers in an attempt to stop the dirty business of crime lord Han Tin Lung, but Han's problem is not only the interference of the Police force, but his Japanese ally Kimura is not happy with his 'cut' in the counterfeit deal and will try to put Donna (a relative of Han) on his side to make Han's business his own property. Both policemen and criminals are highly trained Martial Arts fighters and they will have the chance to prove who has the best Kung Fu techniques.

Ah Lung is a pig farmer and a devoted Bruce Lee fan who is anxious to follow in Lee's footsteps, but only ridiculed for his attempts. He is sent to the city to earn a living working at his uncle's restaurant, but when he arrives, he finds a gang of thugs causing trouble in the restaurant. He takes the chance to prove himself and attacks the thugs, defeating them and saving the restaurant. Soon, he becomes a waiter, and discovers a plot by the same thugs to kidnap a woman he works with. Eventually, he defeats the thugs once again and saves the day.
