Synopsis: Using a white dwarf star fragment, physicist, Ray Palmer, has developed a lens which will shrink inanimate objects when ultra-violet light is sent through the lens. However, Ray has been unable to perfect the process because the shrunken objects always explode withing minutes.
Visiting an underground cavern on a nature hike with his girlfriend Jean Loring and a nature club, Ray becomes trapped inside with the group during a cave-in. Exploring the cave, Ray locates only one tiny opening. He uses the sunlight, beamed through the lens to shrink himself to tiny size. Then using the diamond from his ring, enlarges the opening until people can safely pass through.
Worried that he might explode, Ray hurries back to the lens and enlarges himself back to normal. He is surprised that he did not explode and hypothesizes the cave water may have altered the properties of the lens. When he returns to his lab, objects still explode when shrunk, leaving Ray to conclude that his own body possesses a mysterious force, enabling him to survive the shrinking process.
