A story demonstrating the loyalty of a blind and faithful old sheepdog named Buster, who is always diligent in his duty of guarding and protecting Tilly, the youngest and most vulnerable member of the family when she becomes lost in the Australian bush. By following his nose Buster can easily lead Tilly home, but he can't make her understand what he wants. He stays with Tilly and looks after her all through the night, keeping her warm and warning wild dingoes to stay away until the search party of family and friends, alerted by Buster's barking, eventually find them in the early morning mist.
