1941, all white women and children are evacuated from Darwin. Japanese invasion is imminent. On a tiny Methodist mission on Croker Island in the Arafura Sea, the Superintendent and three Cottage mothers are responsible for 95 stolen generation Aboriginal children allocated to their care by the government. The missionaries are given the option of evacuating but how could they leave these children? However food supplies are running dangerously low and no help comes through the long Wet. February 1942, a message by pedal radio, Darwin has been bombed, the missionaries will now have to move the children off the island themselves. So they begin their perilous journey.
