Gam Chi-Gei

A red headed villain (with a blue headed son), a witch and the warriors and monk that fight the two badguys.

The story is a folk-tale, about the spirit daughter of the god of foxes, forced into service to the god of snakes, falling in love with a human scholar/ priest who happens to know a warrior/ priest who is dedicated to destruction of all such spirits.

A serial killer is loose in Hong Kong, murdering hostesses from high class night clubs. As punishment for their flaky style and lack of discipline, two young policewomen are assigned to work undercover as hostesses to catch the sadist. While solving that crime, they discover who's behind some of the city's drug trade. In trying to halt this enterprise, which they undertake without orders, they must face the crime lord's Japanese hit woman.

Another Chinese Ghost Story copy, also known as Affrighted Romance.

Lam Wai plays the murderous vigilante and Alex Man is the tough cop in this forgotten little masterpiece that has good kick ass action.
