Thanks to the discovery of an anti-gravity metal, Cavorite, two Victorian Englishman decide to tackle the most prestigious goal - space travel. They construct a sphere that will ultimately take them to the moon. On landing, they encounter what seems like an utterly barren landscape but they soon find signs that the planet was once very much alive. Then they hear curious hammering sounds from beneath the surface, and come face to face with the Selenites, a race of insect-like aliens living in a rigidly organised hive society.
