Chris Leeton is tormented but also sustained by his growing need to cross over into the landscape of his aboriginal ancestors. After the night of the flood, his Wiradjuri mother resolves to take her four children away from their riverbank home and her unhappy life with Chris's white father. In the struggle to keep the family together in Sydney's grim commission housing, schoolboy Chris is tender witness to poverty and despair. In time he comes to understand that they are exiles in their own land. He senses that it is his generation which must cross the bridge back to that landscape which defines his people's existence.
