Sydney Fox is a professor and globe-trotting "relic hunter" who looks for ancient artifacts to return to museums and/or the descendants of the original owner. She is aided by her linguistic assistant Nigel and occasionally by her somewhat air-headed secretary Claudia. She often ends up battling rival hunters seeking out artifacts for the money.

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.
