The story begins in a large darkened laboratory filled with intricate machinery and instruments. Half a dozen engineers are seated before control panels, which run the length of the laboratory, while two small slender men stand in the middle of the room looking up at a large screen, a screen that reveals the celestial heavens. The two men follow closely, anxiously, the movement of a pinpoint light across the screen.
