Something evil has awakened beneath a forgotten ravine in the Great Smoky Mountains. After lying in peace for centuries, an ancient deity watches.... David and Miriam Hobbs celebrate their fifteenth anniversary in Gatlinburg, unaware that a violent wraith, Allie Mae, will follow them home on a determined quest for vengeance. Having survived this harrowing experience, David's new friend, John Running Deer, unwittingly aids the desecration of an ancient burial site while recovering Allie Mae's remains from a sacred Cades Cove ravine. What John hoped would be the final gesture of peace in giving her a proper burial turns out to be a terrible mistake. Now something much worse than Allie Mae is on the loose. Teutates, the ancient Gallic entity unearthed, sets out on a murderous rampage. David is called upon once more to find a way to stop the angry demon before it leaves a trail of bloodshed from Denver to the sacred ancient hills of Tennessee.

Buried deep in a ravine in the picturesque Smoky Mountains is a very dark secret. David Hobbs, vacationing with his wife Miriam, inadvertently stumbles upon a small cloth 'keepsake' bag and a broken tooth. A human tooth. Miriam begs David to hand the bag and tooth over to park officials, but he ignores his wife's pleas and secretly keeps the 'harmless' items. The action opens a doorway that had been closed for nearly a hundred years and unleashes hell on earth, or at least hell in the lives of David and Miriam. Following the brutal murder of his best friend in Denver, and an aborted attack on his oldest son, David desperately seeks to understand why a mysterious teenage girl has chosen to terrorize him and the males closest to him. To prevent further devastation to his family and end the wanton bloodshed, he returns to the enchanted hills of eastern Tennessee, where a terrible truth awaits discovery...one that forces him to face the consequences for the unpaid sins of his ancestors.
