Synopsis Meet the Hi-Riders - a gang of jean-jacketed drag racers. Every man a devil-driven death machine in a human demolition derby. They live hard and die hard - screaming demons headed for hell on chopped-down hogs. Mark and Lynn (Darby Hinton and Diane Peterson) get caught up in a story of hatred and revenge after trying to collect on a bet with a Hi-Rider. The Hi-Riders are challenged to a drag race by one of the local hot heads and in a spectacular explosion both drivers are killed. The local boy's father vows revenge. A fantastic stunt-filled chase ensues between the Hi-Riders and the local henchmen. Whipped into a blazing frenzy of violence the Hi-Riders are humping hot steel hogs on a raging rampage through the town. Zip up your leather jacket, kick over the starter and take the ride of your life with the Hi-Riders!
