Using a time machine, an unnamed narrator is sent half a million years into the future in order to investigate the whereabouts of two men previously sent to the same time period and failed to return. Upon arriving, he makes contact with the Amphibians, a telepathic humanoid race, who live in an uneasy peace with the Dwellers, the inhabitants of Earth’s subterranean territories.
