Earth. Post-Apocalypse. 1000 years after the Neutron Wars. Lord Zirpola, the dictator of Helix City, captures Range Guides Kaz Oshay (David Carradine) and Deneer. Range Guides are mystical nomads who have strange powers and who choose to fight for good in the bleak wastelands. Lord Zirpola forces them to take part in his favourite entertainment; the Death Sport - an arena where they must fight to the death on special motorcycles like Roman gladiators. But Kaz, Deneer and others break out and make their escape on the strange motorcycles, trying to cross the lethal desert to freedom. Ankar Moor, a former Range Guide who now serves the evil Zirpola, hotly pursues the fleeing group and now wants their blood!
