In the land of Condon, the deranged Queen Victoria seals the country in behind a huge wall and establishes a "Monarchy of Terror." The intellectuals and sexually liberated are persecuted and murdered. Some of them form an underground movement, the Cult of Perv, led by the Demon Nanny who dies giving birth to Pervirella, who grows at an amazing rate into a beautiful young woman. Whenever her magic necklace is removed, Pervirella becomes a raging nymphomaniac and - hunted by every interested group in Condon - teams up with special agent Amicus Reilly.
