Accompanying the landmark BBC natural history documentary, narrated by Sir David Attenborough.

Every family has its pride.

Kingdom chronicles the real-life saga of four powerful animal families set in Zambia's Luangwa Valley, a land experiencing seismic change. And these aren't just any families.

The valley is home to the fastest growing lion population in the world, the densest number of leopards in Africa, the largest population of wild dogs, and the first hyenas to receive an in-depth collared study. Leopard mother Olimba is on a mission to raise her cubs to adulthood; alpha female of the wild dog pack Storm is fiercely determined to lead her pack to new plains; hyena sisters Toto and Tandala vie to become clan queen; lion brothers evade hunters and lead their pride in the valley.

As their world shrinks around them, the families are pushed closer together until they come head-to-head in a battle against each other for the land.

Featuring stunning full-colour photography, Kingdom charts the tumultuous existence of these real animal characters as they compete to exist in the increasingly threatened Luangwa Valley.
