On the eve of the annual local regatta, family rivalries are aggravated when the Callaghans inform the police that the Foleys are planning a salmon poaching trip. The Foleys wriggle off the hook in Court, but trouble is brewing.
The Major learns he is the patron of the regatta. On his journey to the event, he meets Flurrys friend Dr. Hickey, who persuades the Major to help him raid the butchers shop. Of course, Philippa and the Knoxes arrive as the men are breaking and entering.
