In a series of enlightening, dramatic and moving films, former Royal Marine officer Bruce Parry immerses himself in the way of life of some of the most remote tribes in the world. Parry sets out, not just to observe, but to experience and learn about the lives of these remarkable people. He hunts, cooks, eats and sleeps with his hosts - and even tries their ritualistic drugs. Shedding the trappings of western life, Parry reveals not only the practices and traditions of these indigenous peoples but also their warmth, humour and incredible resilience. Along the way he shares roasted rat cake with the Himalayan Adi; joins the Dassanech, a tribe from the Omo Valley in southern Ethiopia, on a night-time crocodile hunt; leaps naked across the backs of a line of cattle in a Hamar coming-of-age ritual, and, with the Sanema of the Amazon, attempts to become a shaman, by taking a massive dose of psychoactive tree sap. Winning the trust and friendship of people wherever he goes, Parry is able to offer a vivid insight into their world and examine the way in which western influence is encroaching on such remote areas.
