Africa.

In the four years of making this series, we've been to some astonishing places, and seen animals behaving in ways that have never been filmed before.

In this programme, we travel to the four corners of Africa.

From the jungles in the west, to the mountains of the east.

From the ancient south to the deserts of the north.

Revealing extraordinary landscapes.

Looking at them through the eyes of the animals that live here.

The continent's wildlife is the most celebrated on Earth, but it still has plenty of surprises.

We start in the most ancient corner of the continent.

The Kalahari, in Africa's south west.
