A dreamer obsessed with traveling through time builds himself a time machine and, much to his surprise, travels over 800,000 years into the future. The world has been transformed with a society living in apparent harmony and bliss, but as the Traveler stays in this world of the future he discovers a hidden barbaric and depraved subterranean class. Wells's translucent commentary on the capitalist society was an instant bestseller and launched the time-travel genre.
