Within the small Australian Aboriginal community of Nhulunbuy, Djalu Gurruwiwi, famed traditional didjeridu craftsman and player, alongside his sister, Dhanggal, strain to keep Galpu clan traditions safe from numerous internal and external forces. When Djalu's son, Larry, proves to have limited interest in continuing the clan or instrument's legacy, the elders are forced to turn their attention toward the Gurruwiwi grandchildren. Complicating matters is the multi-billion dollar Rio Tinto bauxite (aluminum) mine whose growth has mushroomed over the last fifty years. Djalu and Dhanggal's strategy to move the family out to traditional homelands deep into the bush is complicated by the limited infrastructure and lack of formal schooling for the youth. While attempting to shepherd their clan through economical, environmental, cultural and social pressures, Djalu and Dhanggal Gurruwiwi remain firmly resolved in their mission to maintain tradition.
