The series is set on Earth after an invasion by an alien humanoid race called the Adri. After an attack that reduces Earth to a primitive state, they send a race of killer robots to the planet's surface, "The Beasts", with the task of enslaving any human survivors. She also receives telepathic powers, which enable her to communicate with plants and animals. The same capabilities can now be found in the new generation of humans, but even more powerful than hers, and they are instrumental to the final destruction of the alien invaders.
