Kingdom powerfully tells the true stories of four African animal families in one of the most ambitious projects ever undertaken by BBC Studios Natural History Unit. Filmed over five years in a single spectacular location, the series reveals how the lives and fates of the four families—leopards, hyenas, wild dogs, and lions—are inextricably linked as they vie for a place in a remote and fertile river valley in Zambia. In addition to the intense power struggle between these apex predators, the series reveals how a colorful supporting cast, from mighty elephant herds to vast groups of crimson bee-eaters and marauding baboons, influences the protagonists in surprising and diverse ways.
