Tom is going on holiday and with him on the Broken Hill plane are Kate, a pregnant woman and two businessmen. The businessmen want to look at a certain place which isn't on the route to Broken Hill and the pilot forges the flightplan. They crash and no one knows where they are. One of the businessmen goes for help, but it's stupid - he'll never make it without water. The woman delivers a little baby girl who is very ill. Luke and the woman's husband is out looking for them and finds the businessmen who'd gone for help severly dehydrated. They find the others as well and everybody will be all right, even the little baby!
