Teenage Caveman (2002)

In a dystopian future, the world has regressed into a prehistoric era, with mankind dwelling in caves, led by a ruthless religious figure. Amidst the tribe's survivors, a brave teenager, David, stands up for his violated love, Sarah, by slaying the tyrant – his own father. His act of defiance results in a death sentence, leaving him bound to a pole as punishment. However, in the spirit of rebellion, David's friends, alongside Sarah, orchestrate his release. The group of young renegades flee their primitive life, wandering into the remnants of a once-thriving city. As they battle a ferocious storm, they are rescued by the enigmatic duo, Elizabeth and Neil. Elizabeth and Neil, the last vestiges of a forgotten society, introduce the teenagers to the forbidden pleasures of their tribal past: sex, drugs, and an array of intoxicating beverages. The teens are also exposed to a wardrobe of clothing, a luxury unknown to their previous cave-dwelling existence. However, beneath the allure of these newfound experiences, a sinister secret awaits. The generous hosts, Neil and Elizabeth, are in fact, genetically altered, indestructible mutants. They possess their own agenda for the human race, far removed from the teenagers' understanding. Neil, a genetic experiment, represents the advent of a new breed of predators, while Elizabeth has been transformed by his potent semen. In this post-apocalyptic world, the brave band of teenagers must navigate these alarming revelations, and determine their own destiny. 'Teenage Caveman' is a thrilling exploration of survival, rebellion, and the dark shadows that lurk beneath the guise of hospitality.
