In the first episode, Liz Bonnin joins a thousand elephants - from magnificent bulls to vulnerable orphans - as they come together in a crucial annual gathering in Northern Kenya.

Thousands of zebra face lions, hunting dogs, drought and starvation as they undertake the world's most newly-discovered migration. Braving one of Botswana's most brutal wildernesses they make Africa's longest land migration to reach the rich grasslands of Nxai Pan National Park.

Liz Bonnin leads a team of scientists and film-makers, using cutting-edge technology to attempt something that has never been done before: follow the zebra, on the ground, every step of the way, and reveal the secrets behind this brand new discovery.

Nature's Epic Journeys, presented by Liz Bonnin, follows three iconic animals on three of the world's most breathtaking wildlife adventures. Each must overcome immense obstacles, from challenging terrain to hungry predators and sheer physical exhaustion.
