A fascinating crime saga of a Sino-Vietnamese crime gang. Danny Lee stars as a misunderstood refugee while Ray Lui plays a cop struggling against his own preconceptions to make sure that justice is done.

Wang Chung plays the standard level-headed cop in charge of a rag-tag bunch of misfits and stereotypes (the coward, the playboy, etc.) who are after a drug runner. After their informant is killed, the team turns to a former Triad member (Danny Lee) to infiltrate the gang and bring the big boss down.

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.

This is an atypical police film from 1981 and an opportunity to see a younger Kent Cheng playing a policeman.
