Rescued from alien annihilation, office drone Edward Borman finds himself at the mercy of his savior, who quickly pulls him into hiding as two more glowing creatures appear over the liquid corpse of their fallen brother. A flash of light, and the mess is gone, at which point the two creatures flee into the office. "What are they," asks Borman. His answer? "Dangerous. Very dangerous." A tense game of cat and mouse ensues, with Borman's pistol-wielding protector leading him on an escape from the intruders. In a construction zone, the duo witness a worker being zapped, and are forced to descend to the building's parking garage. There, they see two metallic humanoids working on a device while the glowing creatures patrol. Yaeger reveals that the contraption in question is a "Gravity Engine," and deduces that the building is being used as a magnifier. In a quiet moment, Yaeger explains things to Borman: The invaders are men from Mercury, made of light so dense, it has become solid. Using some nifty technology, he deduces the Mercury Men's plan: To pull the moon into the Earth. (thetvdb.com)
