Aliens have arrived on earth to save the human race from a future catastrophe. But it is up to a small band of determined people led by Edward Lektor, a security specialist, and Evelyn Lin, a beautiful Asian who works for the company that helped bring the aliens to earth, to figure out what the aliens are up to and how to stop them. Complicating their task is the fact that half the human race perceives the powerful aliens as gods and succumbs completely to a new religion of the Devoted.
