The frequently used title An Eye for an Eye was applied to a Chuck Norris martial-arts festival in 1981. Norris plays Sean Kane, a San Francisco cop whose partner is murdered by an Oriental drug ring. Told to keep his distance by his superiors, Kane quits the force and sets out to exact vengeance. When he's not suffering from traumatic nightmares, our hero is single-handedly decimating every one of villain Morgan Canfield's (Christopher Lee) henchmen.
