The people of Earth are visited and befriended by a human-like race from outer space inhabiting massive spacecraft, 50 of them measuring three miles in diameter, hovering over cities throughout the world. These newcomers speak Earth's languages fluently, though they have distinct electronic-sounding voices and are so sensitive to light that they frequently wear sunglasses. They're called the Visitors by the people of Earth. They've come to our planet for resources that we can manufacture for their people to survive in exchange for their vast knowledge of technology and medicine. They become celebrities welcomed by humans worldwide.

Manufacturing ramps up while the Visitors take over media outlets, shaping public opinion for their cause against the world's scientists and any others who might figure out how to stop their domination, registering them to track their whereabouts, and imposing their influence upon the world. Revealed within the tale is that the Visitors are a race of carnivorous reptilians donning elaborate human disguises to suck the Earth completely dry of its water and to harvest humans for food. Kenneth Johnson writes, directs, and produces. Marc Singer, Faye Grant, and Jane Badler star.
