Old Bob, an aging Ute Medicine Man, is destined to fulfill an ancient legend. He and his closest friend, retired Police Officer Jerry Cloud, keep this knowledge secret for over forty years. This secret has its toll on them, and in spite of their lifelong bond, distrust eats away their friendship.
The old shaman's prophecy foretells of a vile, ancient shapeshifter, Nyatt, enlisting skin walkers to steal human souls so that he can escape from an evil portal hidden in the Uinta Mountains. In the summer of 2000, the killings begin and a confrontation with Nyatt is imminent. The shaman convinces his grandson, Manny, who resists the ways of the Ute Tribe, to prepare for an Indian warrior's battle against Nyatt. After Old Bob calls for the gathering of four mysterious crystals, Manny and three of his non-Native American friends unwittingly submit to their part in fulfilling the legend.
They discover the veil between reality and the supernatural is the width of a fly's hair. Untimely deaths, love gained and lost, insanity, human conflict, and inexplicable horrors besiege the band of motley modern warriors. Old Bob is the one chosen by the spirits to face the demonic creature, but has his power grown too weak?
