A small boy, an orphan of the First World War, wanders into the Australian airmen's mess in Germany, on Christmas Day in 1918. A strange boy, with an uncertain past and an extraordinary future, he became a mascot for the air squadron and was affectionately named 'Young Digger'. And in one of the most unusual incidents ever to emerge from the battlefields of Europe after the Great War, this solitary boy was smuggled back to Australia by air mechanic Tim Tovell, a man who cared for the boy so much that he was determined, however risky, to provide Young Digger with a new family and a new life in a new country, far from home.
