Two teenagers foil a plot by their wicked neighbor to misuse the energy from a magical universe existing inside mysterious Brown Mountain. The mythological Gorgons, seething for revenge against the human race for the killing of their sister, Medusa, eons ago by the Greek hero, Perseus, agree to come into the outside world and turn the witch's enemies, both real and imagined, into stone. In order to stop the brilliant sorceress, the twins venture into the realm of light. With the help of the residents living in the miniature solar system, the twins manage to close the wormhole that connects the two worlds after becoming involved in an epic struggle between good and evil.
