Under the moonlit shadows of the Smoky Mountains, best friends Claire Donnelly and Jason Reed set out on a nighttime hike near the historic Mingus Mill. Their laughter and footsteps echo through the tranquil forest, where whispers of the past linger like fragile specters in the air. But when they stumble across an ancient seal buried beneath the mill's foundations, curiosity leads them to a fatal mistake. Breaking the seal unleashes an unspeakable evil. A malevolent entity imprisoned for centuries, its power twisted with rage and vengeance.
As the entity spreads its darkness across the landscape, warping the once serene wilderness into a nightmarish for them, Claire and Jason find themselves the only hope to confront the horror they've awakened. With the help of Cherokee guiding and aiding them, they must uncover the secrets of the entity's origin and battle against time to seal it away once more. But as the entity grows stronger, its chilling grip begins to twist their deepest fears into reality, threatening to break their bond, and their sanity.
