In 1931 Molly led her two sisters on an extraordinary 1600-kilometre walk across remote Western Australia. Aged eight, eleven and fourteen, they escaped the confinement of a government institution for Aboriginal children removed from their families. Barefoot, without provisions or maps, tracked by Native Police and search planes, the girls followed the rabbit-proof fence, knowing it would lead them home.

Their journey - longer than many of the celebrated treks of recognised explorers - reveals a past more cruel than we could ever imagine.
