 Reporters Clark Kent and Lois Lane arrive in the small town of Silsby to witness the drilling of the world s deepest oil well. The drill, however, has penetrated the underground home of a race of small, furry people who then come to the surface at night to look around. The fact that they glow in the dark scares the townfolk, who form a mob, led by the vicious Luke Benson, intent on killing the strange people. Only Superman has a chance to prevent this tragedy.
