In the Australian countryside, five children are best friends, including a set of siblings, an English war evacuee, and aboriginal Neza. They boast to three strangers, Long Bill (Chips Rafferty), Jim (John Fernside) and Blue (Stan Tolhurst), about the mare belonging to the father of one of them. The next day the mare has gone. Suspecting the three men of stealing it, the children set off to recover it.
