George Monbiot travels among some of the most extraordinary people on earth - the Nomads of East Africa.
Rain Pilgrims. God is a blue man who appears to the rain prophet, and without his predictions, the Turkana people would die. Monbiot absorbs nomadic culture, survives being pronounced clinically dead and finds himself at the heart of the last ever graduation ceremony of warriors in the Massai village of Enkaroni.
