When the capsule of the Scoop Mission returns to Earth and lands in the small town of Piedmont, it brings a mutant living being and all the population, except a crying baby and an old man with ulcer, dies with clotted blood. A team of five scientists - the leader Dr. Jeremy Stone, Dr. Charles Dutton, Dr. Mark Hall, Dr. Ruth Leavitt and Dr. Kirkie - are summoned and gathered together in the top secret Wildfire facility. Fighting against time, they try to understand the reason why the old man and the baby survived and research an antidote to Andromeda, the ultimate biological weapon.
