Leon Isaac Kennedy is Doug Russell, an American who steals a shipment of gold in the Phillippines with two Vietnam War buddies, who cut his throat and throw him overboard. Russell washes ashore an island inhabited by two Japanese soldiers stranded there since World War II. They nurse him back to health and he is taught martial arts and the art of the samurai. Back in the States, his treacherous pals, Marelli and Maghee, use their loot and viciousness to muscle their way into Los Angels mafia turf. Maghee sets his sights on Russell's wife, Maria (Leon's real-life spouse at the time Jayne Kennedy), a lounge singer who can't get a gig because Maghee has her blackballed all over LA in his scheme to make her come crawling to him. Russell, samurai sword in hand, hitches a ride on a boat back to America and begins his search for his wife and son; he learns that Marelli and Maghee are the top men in town and he begins slaughtering their cohorts, working his way up the hoodlum food chain. Plenty of action and yucks, including a "touching" montage when Russell is reunited with his wife and son. FIGHTING MAD, not to be confused with the Peter Fonda revenge flick of the same name, is entertaining in a MYSTERY SCIENCE THEATER 3000 kind of way.
