It's the story of a man and his dog. As a man living alone in a post apocalyptical desert, his main goal is to find a female to have sex. The dog is basically trained to find females. In his "quest" he will discover a lot of strange things, especially a subterrean elitist civilization, which is the descendant of the wealthiest gotha, trying to follow a radical morally pious way of life underground (btw this actually inspired the Fallout game franchise). The more you learn about this people, the more you realize their utopia is rather a terrific dystopia ...
