In 1899, Arnold Bedford and his fiancée Katherine Callender – known as Kate – meet an inventor, Joseph Cavor, who has invented Cavorite, a substance that will let anything it is applied to or made of deflect the force of gravity and which he plans to use to travel to the Moon. Cavor has already built a spherical spaceship for this purpose, taking Arnold and (accidentally) Kate with him. While exploring the Moon, Bedford and Cavor fall down a vertical shaft and discover to their amazement an insectoid population, the Selenites, living beneath the surface.
