World Gone Wild (1987)

"Fifty years after the end of the world, the only ones left are nuked out, zoned-out burnouts. The wildest adventure of all is about to begin."

In the nuclear ravaged wasteland of Earth 2087 water is as precious as life itself. The isolated Lost Wells outpost survived the holocaust and the inhabitants guard the source of their existence. Now an evil cult of renegades want control of their valuable water supply. And the villagers are no match for such brute military force. Only one man can help the stricken community - a mercenary living in a distance cannibal city. But even he, and his strange henchmen, may not be able to survive in the world gone wild.
