||The Earth's climate is freezing, caused by the sun's inexplicable, sudden dying. Rex and Speed must solve the mystery. An alien race in the ionic atmosphere is responsible, focusing Black Ray on the capital city of Earth. The aliens are lead by one named Roj, who plans to enslave the Earth and land their space-city for settlement. The aliens require cold that will kill all human life on Earth. Rex rigged up a powerful lamp to attack the light-allergic aliens, blowing up their planetoid before they can use their Black Ray again to destroy the Earth's inhabitants.
