Join two aliens, Fedhisss and Urr, traveling in separate space vessels, on a joint mission to seek out and explore new regions and new life forms in the universe. During their second planetary stop, however, Fedhisss decides that he also wants to improve the overall quality of life in the universe, and he intends to do so by eradicating any concentrations of consciousness they may come upon that Fedhisss deems unworthy of existence. With that in mind, Fedhisss then wreaks total havoc on the planet they are visiting by destroying all of the life forms existing there. And when he sees that Urr is now strongly determined to stop him from making any further judgments, Fedhisss departs in his own ship, trying to leave Urr behind. Using the guidance system on his ship, Urr then manages to track Fedhisss to his next landing, the planet Earth.
