In 1931, Molly and her younger sister and cousin, Gracie and Daisy, were three half-caste children from Western Australia who were taken from their parents under government edict and sent to an institution, were taught to forget their families, their culture, and re-invent themselves as members of "white" Australian society. The three girls begin an epic journey back to Western Australia, travelling 1,500 miles on foot with no food or water, and navigating by following the fence that has been build across the nation to stem an over-population of rabbits.
