In this science fiction adventure, the evil warrior Kyla (Richard Moll) has stolen a sacred crystal that is the source of all life on the Planet Sintaria. A similar crystal exists on Earth, and Ladera (Brigitte Nielsen), a mighty soldier for the forces of good, sets out to claim it before it can fall into Kyla's hands. When she arrives on Earth, she discovers that the unscrupulous Jed Sanders (John H. Brennan) has already grabbed the crystal, and may sell it to crime boss Victor (Fred Asparagus) to pay off his debts. Filmmaker Sam Raimi appears in a bit part.
