Is there life out there? Finally we know. Beause they are there. Alien spacecraft with humanlike passengers have come to Earth. They say they come in peace for food and water. The water they find in our reservoirs. The food they find walking about everywhere on two legs.

Fifty spaceships, each three miles across, hover ominously above Earth's major cities. The Visitors that emerge are humanlike in appearance and extend the hand of friendship. Our planet's resources are just what these aliens need to survive. And for its future survival, unsuspecting humankind will need... a miracle!
