For 800 miles, by canoe and on foot, through untamed and uncharted rainforest, the Blairs seek the last of the nomadic Punan Dayaks, the free-roving masters of the interior, the "dream wandering" tribe who were believed to no longer exist. The brothers struggle inwards, plagued by torrential rain, quicksand, leeches and virulent insects. Eventually they find and live with the Punan Dayaks, where they are initiated into the spiritual mysteries of the “dream wanderers”. Lorne and Lawrence join the "dance of the hornbill" and get tattooed with the symbol of Aping. This, the Punan shaman explains to them, they will now now carry wherever they go to amongst the tribes of man, as a reminder that all Life is part of a Single Tree.
