The actress follows the river into the deserts of Northern Sudan, where she meets the survivor of a crocodile attack and goes in search of the creature. She is then introduced to the treasures of Nubia, an ancient kingdom of Africa ruled by the little-known Black Pharaohs, before visiting Sudan's capital city Khartoum, where she talks to nomads who live in the remote sub-Saharan desert.
