Cocooned by wealth and private schooling, John Willmott, 55, and his three children - Cyrus (12), Emile (nine) and Eliane (six) - have lived a charmed existence. But now mum Rafia, 33, wants to burst their privileged bubble, hoping the whole family will learn some valuable lessons. In the Himalayas, the Mongolian steppes and deep in the Papuan rainforest, she seeks out places and people untouched by the modern world. Theirs is an epic journey that includes encounters with the Dalai Lama and one of the world's remotest tribes, but will it make a lasting impact on their lives?
