Mr Shepherd is taking Aunt Sally on a canal boat holiday through West Chester in order to see a museum owner, Mr. Pursglove, who he believes wishes to purchase her. However, before he can leave, Worzel spies her in the back of the car and decides to jump in and stow away with them. At the boatyard he gets out of the car to explore and ends up seeing a face he recognizes - Saucy Nancy. He climbs aboard her boat, but unfortunately it’s the same boat Mr Shepherd has hired, and when Aunt Sally gets aboard... of course, a fight ensues!
