Perry Rhodan, leader of the Third Power, had managed with the aid of extra-terrestrial super-science to unify the warring factions of Earth. Humankind now stood at the beginning of its greatest Golden Age. But suddenly there came a new enemy, an alien force whose aim was to destroy all other intelligent life in the universe. Their most terrible weapon was the ability to take over human bodies with their minds, while imprisoning the human minds within their own monstrous insect-like bodies. No beings in the galaxy had ever managed to survive against the Mind Snatchers. Perry Rhodan led his telepathically trained Mutant Corps against them, and mankind's fate hung in the balance.
