When an alien entity lands in the Southern Appalachian Mountains, a clairvoyant psychology professor, a drunken dirt farmer, and a disillusioned tycoon must team up to stop it before the infection spreads. It falls from the heavens and crashes to earth in the remote southern Appalachian Mountains. The alien creature feeds on the surrounding organisms, exploring, assimilating, and altering the life forms it encounters. Plants wilt from the contact, trees wither, animals become deformed monstrosities, and people become something both more and less than human. Tamara Leon is a psychology professor who sometimes sees the future. When the strange phrase shu-shaaa enters her mind, she senses a telepathic force that threatens her family and the entire world. Chester Mull, a mountain dirt farmer, is suspicious of the green glow up on the ridge, and he doesn't take kindly to trespassers. His neighbor Herbert DeWalt is a reclusive millionaire whose spiritual search has led him nowhere. The trio teams up on a mission into the forest to face the alien in its secluded cave. The alien doesn't want to destroy the world. It only wants to survive. But so do the people whose metabolism has become food for an otherworldly reaper.
