Trek - Spy on the Wildebeest

Each year over 1.2 million wildebeest travel across the vast Serengeti plains and Kenya's Masai Mara on a 1,800 kilometer circular journey, relentlessly followed by every big African predator. Revolutionary spy cams - airborne, swimming or disguised as rocks, skulls or dung - reveal the Great Wildebeest Migration from entirely new perspectives. This 2-part series focuses on the growing-up of a calf as he takes his first steps, faces his first deadly perils and tries to cross crocodile-infested rivers. It combines natural humor with exciting drama and gripping music.
