Remember back in 1953 when those extraterrestrials invaded Earth and things looked pretty grim until common bacteria killed them all? Good times! The bad news is, that "killed" thing? Not so much. The aliens were just forced into a state of deep hibernation. They're waking up now and, boy, are they peeved. And they've learned how to assume the appearance of humans as they try to rally their troops for a new war. The fate of Earth may very well rest in the hands of a small yet courageous band: astrophysicist Harrison Blackwood, paraplegic computer wizard Norton Drake, microbiologist Suzanne McCullough and military man Paul Ironhorse.
