A pack of wild dogs in Zambia's Luangwa Valley lord over a home range of nearly 200 square miles. However, trouble is brewing: a nearby clan of hyenas are determined to make life difficult for the dogs, from stealing their food to hunting their pups. It's a turf war with deadly repercussions--and that's even before the lions become involved.

In the depths of the Luangwa Valley, an unusual confrontation brews between two unlikely and evenly-matched opponents: an elite pride of lions, and a 300-strong herd of buffalo. Male buffalo can weigh up to a ton, have thick 2-inch hides and lethal horns. It's an epic stand-off between two formidable adversaries, with neither willing to cede ground.
