Davy David, an orphan, lives by his wits in the dead-end town of Brownvale. When a stray dog called George turns Davy's life upside down just days before Christmas, he sets in motion a chain of events which forces them to flee. A mischievous wind blows the two of them to a boarded-up museum on the outskirts of town where they meet the elderly recluse, Miss Flint. She has planned one last adventure before her time is up and hires the reluctant Davy and George to escort her.
