On the distant planet Centaria in the far side of the galaxy, a ruthless and powerful being known as Kyla has vowed to enslave and destroy its people. Two powerful crystals holding the key to omnipotent power are all he needs to accomplish his evil purpose. With one stone at last in Kyla's possession and the revolutionary guerrilla force seemingly defeated, Ladera enters a space and time doorway that leads her to 20th century Earth to find the hidden, missing crystal. Empowered with super-human strength and weapons from her home planet, Ladera meets Jed Sanders, an opportunistic fortune hunter who has unwittingly discovered the all-powerful crystal. But Kyla has followed her to Earth and will stop at nothing to retrieve the matching crystal to the one he already possesses and rule the solar system.
