Yellowstone National Park is a world of predators, scavengers and opportunists. In this vast and complex kingdom, two dominant predators reign supreme: the grizzly bear and the wolf. Size and power square off against speed and teamwork, as mighty grizzly bears contend with powerful packs of wolves for control of the food supply. As these two fierce competitors test their strategies for survival against each other, an entire food chain of scavengers survive in their wake.
