The monsters of Earth were under the technological spell of the maniacal alien race from the planet Kilaak, and their dominion over human civilization appeared imminent. However, it was discovered that their mind-controlling signal was emanating from a remote lunar base in the Alpine Valley of the Moon, and the powerful Moonlight SY-3 was sent to investigate and destroy the Kilaak's transmitter. As the rocket descended into the Cassini Crater, a raging conflagration enveloped the vessel, for the Kilaaks had ignited their massive torches. The damage would have been immense, had it not been for a modest lunar vehicle dubbed the Exploration Car. The astronauts piloted this moderately sized, all-terrain rover to the entrance of the aliens' subterranean base. The Exploration Car's lasers were fired, and the facility's entrance was destroyed!

As the Kilaakian reverted into their slug-like metallic forms, the pilots of the Moonlight SY-3 began to saw away at the transmitter. It was of no use; they could not penetrate the stem of the device. The astronauts thought quickly and came to a solution! Removing a laser from the ground car, the transmitter was fired upon. Though it appeared as though the circuitry would overheat, the machine was finally sent toppling to the ground. The mind control was severed, but the war was not yet won. The ultimate battle was still on the horizon...
