A Tibetan refugee dies far from home, his last wish - to set foot on his native soil again - unfulfilled. Years later his son, a New York-based artist, embarks on a remarkable journey, to cart 20,000 kg of Tibetan soil out of the country - and the Chinese authorities won't make it easy. Tenzing Rigdol's soil project is a powerfully touching attempt to reunite exiled Tibetans with their homeland.
