Just finished this film recently, and I'll have to say I was quite impressed with the quality of this film. Knowing this had a lower rating on IMDB, I expected something within "so bad it's good" territory, but instead I got a fairly decent crime thriller / slasher that embodies the cheese of the mid 80s.
To put the plot simply, recognizable actor Charles Napier (from First Blood, Hard Justice) plays a grizzled, alcoholic detective who pursues the mad killer Chuck Sommers (played by the man, Robert Z'Dar), who preys on prostitutes. Following this are iconic scenes of dialogue, and some decent action scenes as well. To add, asian actors George Cheung and Eric Lee make apprearances in this as well.
Overall I rate this a 6/10 for a flimsy but decently fleshed out story, Z'Dar, and that good old 80s cheese.
