Produced in the Autumn of the Golan-Globus collaboration, Avenging Force serves as a vehicle for American Ninja costar Michael Dudikoff. Cast as a retired secret service agent, Dudikoff runs up against a sinister right-wing political organization called the Pentangle. He comes to the aid of his best friend Steve James, a black political candidate who has become a target for the Pentangle's henchmen. Impressed by Dudikoff's martial arts skills, the Pentangle leaders try to convince him to join their cause-and to ensure his cooperation, they kidnap his little sister Alison Gereighty. Avenging Force concludes with a violent Enter the Dragon-style mano y mano squareoff between Dudikoff and the Pentangle flunkeys. The film's finale is "open" enough to allow for a sequel, which has yet to appear.
