Two Worlds Collide… Centuries have passed since mankind vanished from the Earth, and in that time, the Wolves have risen to inherit the title of "Alpha Predator". They have lived in peace and thrived for generations. But that is all about to change. The Wolves tell stories, of beings that walked upright, the Walkers, who would one day return to ravage the Earth and take back their "Alpha" crown. The young wolf-prince, Ukita, along with many others of his Pack, dismiss these stories as mere fiction, until one night, when he himself meets a young Walker by the name of Ahote, who is destined to become leader of his Clan. Faced with the looming shadow of a violent war between their two clans, Ukita and Ahoté must work together to put an end to the hostilities between their races. The fate of both their species depends on it.
