A lizard-like alien race, known as the Visitors, have invaded Earth. They came claiming to be friendly, but they had ulterior motives for their visit to Earth. The aliens appeared usually as humans, and were welcomed to Earth by the humans who did not yet know their true intentions. Nathan Bates, a biological scientist, makes a deal with Diana, the leader of the Visitors, in order to use her alien technology, and profit from it, while a band of rebel resistance fighters, led by Dr. Julie Parrish, photojournalist Mike Donovan, and mercenary Ham Tyler, know that Diana, and her kind, have more sinister plans in store for Earth and its inhabitants, and work to destroy them.
