In the vast kingdom of Yellowstone National Park, two predators reign supreme: the grizzly bear and the wolf. Size and power square off against speed and teamwork, as mighty grizzlies contend with powerful packs of wolves for control of the food supply. Normally these two hunters would rule their ranges uncontested, but in Yellowstone they must share resources, or face starvation.
