When a young coyote named Cain is cast out by his pack, he must learn to survive in a wilderness both beautiful and treacherous. As the coyote's journey unfolds, he'll encounter a large cast of wildlife characters in what has been called America's own Serengeti. Set against the natural beauty of Yellowstone's changing seasons, from the steamy geysers in winter to the raging fires of summer, Cain's year-long adventure of hardship and triumph will culminate in a final life-or-death confrontation with his original pack.
