 Clark Kent and Lois Lane travel to Silsby, Texas, site of the deepest well ever drilled. But when they arrive, the well is being shut down and the oil company manager present isn t saying why. Meanwhile, two short beings with large heads and furry hands come up from the well to explore. Luke Benson leads a mob of townspeople wanting to kill the "unknown people." Despite Superman s efforts to calm things down, the mob has tracked the two creatures to the top of a dam, trying to kill them. What the mob doesn t know is the creatures cause things they touch to glow in the dark -- and may be radioactive.
