The famous spy-cams turn their attention to nature's most awe-inspiring event - the great wildebeest migration. Trek features a cast of literally thousands, as countless wildebeest, zebra and antelope are joined by the hyena, leopard, jackal, cheetah and crocodile which prey on them. To personalise this story, remote cameras follow the fortunes of a baby wildebeest and a young zebra. Each has a very different story to tell. The epic 3000 kilometre year-long circular journey combines natural humour with high-octane drama, and over twenty mobile and remote cameras provide saturation coverage.
