Each year over one million wildebeest and a quarter of a million zebra and gazelle migrate on Tanzania's Serengeti Plains ? one of the most spectacular events in the natural world.
Nature's Most Amazing Events tells the story of the epic trek of herds that follow the rains to fresh pastures and the tale of the predators they leave behind.
The crew captures the desperate plight of a single pride of lions over an unprecedented year of filming to reveal a different side to the Serengeti. Rather than being a predators' paradise - as it is so often portrayed - it's a land in constant change, where wildebeest follow the rains leaving the lions to tough it out.
