2/3. Crossing Ethiopia's Omo River in a dug-out boat brings the intrepid Bruce Parry to the remote region inhabited by the Hamar people, whose young men have to prove themselves by jumping over a line of cattle. Will the Royal Marine-turned-explorer have the nerve to join in this hazardous ritual - especially as it involves being naked and smeared with cow dung? Producer James Smith : Series producer Steve Robinson
