For the first time, a human herd of 20 elite Americans joins the great wildebeest migration across the Serengeti in Tanzania. This wild bunch of survivalists, fitness fanatics, scientists, hunters and farmers, will attempt this feat without tapping out due to exhaustion, hunger or injury. They must use their expert survival skills to navigate North without a map or compass, carry only limited food rations, and survive encounters with the world's deadliest predators as they cross 200 miles of brutal terrain. Do they have what it takes to reach the Mara River with the wildebeest, or will Nature tear them apart?
