Each spring, in a desperate bid for survival, 1.3 million wildebeests race hundreds of miles north from the dry southern Serengeti plains to the lush grasses of the Maasai Mara in Kenya. It's an incredibly dangerous journey through a landscape dominated by apex predators, including lions, leopards, hyenas and crocodiles. Tens of thousands of wildebeests won't make it - so how will humans fare? National Geographic Channel's new series "Mygrations" follows a team of 20 men and women in a feat that has never been attempted, as they set out on foot, unarmed and without a map or compass, to follow in the footsteps of the wildebeests. The human herd must cross hundreds of miles of scorched savannah - where water, food and shelter are hard to find but lethal predators roam unchecked - to reach the Mara River, the pinnacle of the wildebeests' death-defying quest for life.
