Groundbreaking wildlife documentary, narrated by Sir David Attenborough, that uses an array of spycams in the air, in water, and disguised as rocks, dung and skulls to follow the annual African wildebeest migration. As they begin their 3000 km circular journey, the wildebeests soon become the target for all the main African predators, including hyenas, cheetahs, jackals and crocodiles. The film follows the fortunes of a young wildebeest and a young zebra as they embark on their journey, each trying to survive the treacherous times ahead.
