Many centuries ago, one alien ship crashed on earth. The surviving aliens were defeated by a local Indian tribe. The modern day aliens attempt to acquire the ship to assist in their subjugation of the planet.

Harrison is kidnapped by a unique modern artist named "Quinn", who's actually one of the aliens being hunted by his kind. He's mysteriously immune to Earth's bacteria, so the other aliens want to learn his secret through dissection. Quinn wants to set up a dialogue with Earth's leaders to arrange a "peaceful" takeover of the planet as opposed to an all-out slaughter of humanity.
