Follow famed paleoanthropologist Richard Leakey and his wife, Meave, daughter Louise and their colleagues as they work in the arid northern regions of Kenya's Turkana Basin to unravel the mysteries of human evolution. While one of he Leakeys' goals is to demonstrate the complexity and truth of human evolution, they also seek to show how the qualities that we proudly call human were all born in Africa. The story that emerges in the film is exciting, emotional, contemplative, occasionally funny and, in the end, transforming. This is Africa at its most beautiful and harshest.
