Series in which six athletic adventurers from the west compete for glory against tribal champions in some of the remotest corners of the globe, with the ultimate aim of being crowned the last man standing. In southern Ethiopia they take on the deadly sport of Suri stick-fighting, but before they can enter the ring they must learn to live with a tribe whose way of life has barely changed for hundreds of years. This means a spot of tribal scarring and some internal cleansing known as the Dokai.
