A mysterious martial artist is going around and killing martial arts masters with his unique style, Tiger Claw. Two police detectives, who're also martial arts experts, use unorthodox methods to track down the serial killer.

Somewhere in an apocalyptic future, where the rich live underground and the poor are left to fend for themselves on the surface by forming gangs, corrupt members of an underground security force plot to destroy the surface.

The Tiger Claws killer is broken out of jail by a former colleague, who acquires a large shipment of weapons and schemes to open a portal to the past into an ancient martial arts temple.

When a psychotic martial artist called Stryker resurrects the long-dead spirits of three ancient Chinese master assassins in an effort to take over the New York underworld, it's up to supercops Tarek Richards and Linda Masterson to stop him. However, it's not so easy to battle the undead, and though Richards apparently holds within him the key to defeating these "Masters", he will need the guidance of Stryker's former master to aid him... let the battle begin.
