Billy Lau Nam-Kwong (born 3 April 1954) is a Hong Kong film actor. He is best known for playing the Police Captain in Mr. Vampire (1985), and went on to be cast in similar roles. He has appeared in many comedy and horror films.
Following his defeat by Master Ip, Cheung Tin Chi tries to make a life with his young son in Hong Kong, waiting tables at a bar that caters to expats. But it's not long before the mix of foreigners, money, and triad leaders draw him once again to the fight.
When a former actor moves into an apartment building with the intention of commiting suicide, he is saved by a Taoist priest who used to specialize in hunting Chinese hopping vampires: or Jiāngshī. Elsewhere in the building, a woman turns to a specialist in black magic to bring her husband back to life.
The Hong Kong super-cop must stop a group of blackmailing bombers at the same time that the villains of the first Police Story are out for revenge.
