Description
A scientist sees a flying saucer land and is overpowered by the larger Martian. Since the creature thinks he's dead, he assumes his appearance and lets slip that only infrared rays can detect his disguise as he gathers information for a planned invasion of Earth. After he departs, our hero, who was only stunned, resolves to alert the authorities but they don't believe him. He builds a device that will alert him to the presence of the creature in his disguise and tracks him to an office building. The device goes off in the presence of the night watchman and the alien shifts into the more powerful Martian form, forcing our hero to flee. He rolls to the side as the Martian charges forward and plunges to his doom down the elevator shaft. Our hero then removes his disguise to stand revealed as a Venusian and affirms their pledge to defend the beloved sister planet Earth from the dangers of outer space.
