Frank Shatter (Chuck Norris) and Calvin Jackson (Calvin Levels) are two Chicago Police detectives sent to investigate the brutal murder of a rabbi. As the investigation begins, Shatter and Jackson are summoned to Israel for questioning. Upon arrival, they realize that they are, in fact, pursuing a supernatural being – Satan's emissary, Prosatanos – who tried to wrest control of the world from God during the crusades. Prosatanos, however, was stopped by Richard I of England who trapped him in a subterranean tomb. During this encounter with King Richard, the source of Prosatanos' power – his scepter – was shattered into nine pieces which were subsequently sent to nine holy places around the world. These pieces remained safe until the end of the 20th century when Prosatanos was inadvertently freed from the tomb by two unsuspecting grave robbers. Prosatanos eventually collects all nine pieces of his scepter. Detectives Shatter and Jackson must now fight him to save the world.
