The Oz Valley in the Alps more than 5300 years ago. A Neolithic tribe made its home by a small river. Their leader, Caleb, was in charge of guarding the altar of the tribe, Tineca. While Caleb was out hunting, the settlement was attacked, and all the tribes, including Keller's wife and children, were brutally killed, and only one newborn survived. What's even more frightening is that Tineka is also missing! When he finally found the murderer of the tribe, his biggest challenge was how to save himself.
