Dr. Jeremiah Morley is concerned about an imminent nuclear war. He organizes an expedition of scientists and has them use a large atomic-powered tank-like boring machine, called the Cyclotram, capable of drilling down deep through the Earth's surface in order to find an underground environment where humanity could escape and survive a future nuclear holocaust.
