Kristen keeps Jefferson's memory alive by working as a ranger for the preserve, staying close to the mountain they both loved and his best friend, Bennett, now serving as a local police officer. After Blythe dies though, her surviving son Joshua claims back the land to break ground on a resort and spa, desecrating the area and its natural beauty.

In the process, an ancient creature charged with protecting the earth awakens-the Pine Mountain Devil. With an appetite for the flesh of anyone who messes with Mother Nature, bodies on the construction site begin piling up in the most undignified manner, reflecting their transgressions upon the planet.

Bennett and his female partner, Leoni, have no idea who--or what--is causing these gruesome deaths, but when Kristen pays a visit to the Paiute-Shoshone tribe's environmental director, she learns the legend of a centuries-old creature molded from the earth and tasked as its keeper.

Kristen feels a strange kinship with the creature, but when people close to her start to fall victim too, including her new love interest Leoni, she and Bennett lure the devil out of its lair for a final showdown. Kristen must decide whether to continue protecting the Devil in order to preserve the land she loves or kill it to save the people she loves.
