It's known as the coliseum of the wild: Savute. It's a small tract of land in the corner of Africa's vast desert, where three hunting zones meet at a dead end swamp surrounded by dense, thorny desert. Here, big cats meet big prey in the harshest of landscapes, and success depends on how well the predators adapt to the tough environment around them. Enter the warzone and watch as lions battle nomads to protect their territory, hyenas scavenge for easy meals, and a wily leopard quietly profits in the shadows.

Two East African rivers stand in the way of a massive migration. Over a million wildebeest and thousands of zebras will be forced to cross the Grumeti and Mara Rivers in order to complete their epic annual journey, and every crocodile knows it. Discover the very different hunting strategies crocs must use to attack their prey, based on the demands of the ever-changing waterscapes they live in. As trenches shift and levels fluctuate, see how these fierce reptiles adapt to the rivers' wild tempers to become ultimate predators.

Clouds are forming over the dry plains of the Serengeti and the dinner bell is about to ring for the big cats of Ndutu. The wet season will attract more than a million wildebeest and thousands of zebras, but getting to them is never easy. The area is diverse, not just in prey, but terrain, and each battle zone comes with its own challenges, including steep inclines, maddening mud, and total exposure. See how a pride of lions and two cheetah families tailor their hunt to the landscape and use it to their deadly advantage.
