The plot centers on a cyborg woman named Ivy, who defends the entire universe from enemies using her built-in evil-sensing computers. An enemy infects her with a virus. Now, the only one who can save her is Diatron 5, a mecha shrunk to microscopic size that enters her body to fight the bacteria. Two kids, a battle station called the "Star Wars", and Diatron's inventor join her in the battle against evil. The evil forces consist of an androgynous woman named Mary, her blue-skinned brother who looks suspiciously like Spock, and their fleet of robots and forest-green, demon-like aliens.
