Troy (5) and Sabia (3) are playing happily on the hot, dusty desert floor in the north west of Australia in 1957 when their world is shattered by two faceless visitors. Thirty years later Sabia is a successful lawyer in Australia facing a battle with leukaemia while, half a world away in America, her brother Troy sits isolated in a prison cell accused of murder. Death row stares him in the face.
