Isaac Hayes puts his gun where his groove is in his role as hard-case bounty hunter Mack Truck Turner, three years after composing the legendary score for Shaft (1971). Ex-football star turned skip-tracer, Turner specializes in bringing in the criminals police are too scared to chase, and when he's hired to capture sociopathic pimp Gator (Paul Harris), he finds himself confronted by the most vicious killers in the underground scene. Little does Turner know that Gator's woman, Dorinda (Nichelle Nichols), has a deep-running cold streak of vengeance, and has hired ruthless hit man Harvard Blue (Yaphet Kotto), as well as a legion of other like-minded and equally determined assassins, to snuff out Truck's supercharged motor once and for all. It's now up to Truck to keep his cool long enough to get to the source of the seemingly endless stream of bullets that come at increasingly unsettling intervals.~ Jason Buchanan, All Movie Guide
