Beneath a waterfall on a remote Tasmanian river, Aljaz Cosini is drowning. Beset by visions, he relives not just his own life but that of his family and forebears. He sees his father, Harry, burying his own father, Boy. He sees Boy himself as a young man, and his Auntie Ellie, chased by a cow she believes is a Werowa spirit. In the waters that rush over him Aljaz finds a world where his story connects to family stories that are Aboriginal, Celtic, Italian, English, Chinese, and East European what he ultimately discovers in the flood of the past is the soul history of his country.
