Babs Weston agrees to marry adventurer Richard Forestall before his hasty departure, accepting his ring and promising to be faithful. Richard returns to find that his fiancée has become a "victim of jazz" and is engaged to two other men, one of whom is not yet divorced. He leaves Babs and visits his parents on their island in the Caribbean Sea, where, by coincidence, Babs and some of her thrill-seeking friends become stranded. Richard proceeds to reform the young wastrels by giving them useful occupations, and wins Babs over to a more healthful life.
