In accordance with the Navajos' legend, a thirteen year-old boy will finish with the curse of the powerful Skinwalkers, a.k.a. werewolves. The half-breed boy Timothy is raised by his human mother Rachel and protected by his Skinwalkers relatives since he was born. His grandmother Nana, his uncle Jonas, his cousin Katherine, her boyfriend Adam and their friend Doak have kept the secret about his bloodline and neither Timothy nor Rachel know the tragic curse. A couple of days before Timothy's thirteenth birthday, a pack of evil Skinwalkers that had tasted blood leaded by the evil Varek chases the boy while his family protects him.
