This is director/martial arts star Frankie Chan's unofficial remake of the Kinji Fukasaku film SHOGUN'S SAMURAI (1978). Instead of Japanese samurai in a period setting, we get modern day Chinese gangsters battling each other for the position left vacant after the mysterious death of their head honcho.

A soldier from Mainland China arrives at Hong Kong to look for his estranged sister and finds out that she has been forced into prostitution by a criminal organization.

Chu Yu (Eric Tsang) is a homicide detective who accidently stabs his girlfriend while wrestling with a murderer. The killer returns later and squeezes her wound until it ruptures, causing her death. But the wily Chu Yu photographs his girlfriend's corpse in a wedding dress, tricking the killer into believing she is not dead and causing him to return for a second try. When he does, Chu Yu is waiting, having rigged the corpse like a marionette and causing it to shoot its own murderer. Co-starring Danny Lee, as Officer Li Ta Hsiu, and Dick Wei in this decidedly offbeat attempt at gallows humor which works extremely well under the direction of action specialist Frankie Chan.

Hong Kong, Hong Kong is the story of a young woman, Man Si Sun, who has arrived illegally in Hong Kong from mainland China, and Kong Yuen Sang, a young man who is a gambler and wannabe boxing champion.
