WARRIOR OF THE LOST WORLD

The Rider arrives on his advanced motorcycle equipped with an artificial intelligence computer called Einstein. He crashes but manages to pass through the "wall of illusion" where he is brought back to health by the Enlightened Elders. They have chosen him to lead their fight against the evil Omega, an Orwellian state run by the evil Prossor. The Elders are allied with a resistance movement called the Outsiders. The Rider first helps Nastasia and the other Outsiders by rescuing McWayne, Nastasia's father and leader of the Outsiders. While the Rider and McWayne successfully escape, Nastasia is captured and subjected to brainwashing by Prossor.

The Rider gains acceptance from various Marginals (Amazons, martial artists, truckers, punks, soldiers, Omega defectors) by winning in the ritual brawl which determines who is the strongest. The Rider and the Outsiders launch their final attack on Prossor's regime, but are intercepted by the Omegas and a giant armored truck called Megaweapon. As the rebels destroy the Omega patrols with their cars (Ford Taunus TCs), helicopters, and tankers, the Rider manages to destroy Megaweapon by short circuiting it, but not before his supersonic speedcycle is crushed under the truck's wheels. The Rider and McWayne storm Prossor's headquarters where they face the dictator himself and a brainwashed Nastasia. She wounds the Rider, but when ordered to kill her father, she rebels, turning on Prossor and shooting him instead. The Omega have been overthrown, and the Outsiders and Marginals celebrate, as the Rider prepares to move on with his repaired speedcycle.

In a twist, it is revealed that the man Nastasia shot was actually a cyborg clone. The real Prossor is still alive, flying away with an unnamed traitor of the New Way (Fred Williamson), plotting revenge against the "animals" that defeated him.

The Rider and McWayne defeat Omega’s forces and apparently kill Prossor with Nastasia’s help, only to discover the real Prossor is alive and plotting revenge as he escapes.

The film’s ending delivers the overthrow of the Omega regime and the liberation of the Outsiders, but subverts ultimate victory by revealing Prossor’s survival through a cyborg double. This twist leaves the threat lingering for the future, maintaining the story’s pulpy, serialized spirit and aligning with its themes of ongoing resistance.
