The year is 2020 and the setting is post-nuclear holocaust Texas. It's a dusty, nasty world now as can be seen in the opening scenes when a gang of outlaws rape and murder innocent nuns at a mission. They then crucify the priest. Their debauched reveling is interrupted by roving rangers who engage the villains in a blood-soaked, bone crunching fight. The rangers manage to save a terrified young woman from the melee, and the heroic leader and she fall in love and head for the peaceful land she describes to him.
Years pass. The hero and the girl are married and she is pregnant. Trouble erupts when a megalomaniacal Neo-Nazi dictator and his cruel minions attack the heavily fortified refinery and begin trying to convert the hapless workers to his insane idea of the New Order.
