A diverse group of scientists, including a woman referred to in expository narration as an "ardent feminist," form the Society to Save Civilization. Using a burrowing craft (the Cyclotram), they embark on a journey to the center of the earth to seek out a safe haven for civilization in the event of nuclear war. Ultimately, it is decided that the earth's core just isn't a very habitable place and peace is the only true solution to the world's problems.
