Johnny and his family have moved from the big city to Bishop Falls. Finally, he finds the courage to ask strangers to play. His worst fears are realized though, when the local boys make fun of him and his "fancy" clothes. The postman intervenes, handing Johnny a parcel. He brings it to his father who shows him a picture of a Gipsy Moth, a bi-plane, and hands him a white silk scarf. The rest, his father promises, will be a big surprise. And what a surprise it is! Shortly after, a Gipsy Moth comes in for a landing in a nearby field. It is piloted, he discovers, by his uncle, Arthur Sullivan, who takes him up on a great adventure. Johnny is no longer an outsider. What he does next, however, is what makes him a hero.
