In a supreme test of endurance, skill and courage, six Western men journey to the most remote parts of the world to live with indigenous peoples, to train with them, and to take part in their ancient sporting festivals. They are some of the toughest events in the world. From wrestling deep in the Amazonian rainforest to bullock racing in India and pig fighting on the Nicobar Islands, the six must play by local rules. But their experiences are much more than a sporting challenge; the adventurers enter the very heart of local societies, becoming part of them and performing all the rites and rituals, however dangerous they may be. How will our adventurers cope when pitted against the locals… and each other? Do they have what it takes to gain the respect of the tribe, to really become one of them?
