Buster Strong, a young ”cowboy” from the outskirts of the Milky Way, is working on a genealogy project. He arrives at the enormous, artificial hub of the galaxy, where he is thrown into an orgy of events and culture shock. Behaviors and morals differ from what this hillbilly is accustomed to, and he doesn’t like them.

Meanwhile, a dissident organization disguised as a criminal group is working behind the scenes. A sudden and drastic fate befalls Buster, and mysteries deepen: what happens to Buster, and what are Strush and Clarifyrion?
