Clarence has to get his pig eating again or he will lose the Fattest Pig prize to his fiendish rival. Meanwhile, Connie demands he put a stop to his niece Angela's love affair with cowboy Jimmy.

Anxious to impress the wealthy Schoonmakers, Connie hires Baxter, a personal secretary, to put a shine on Blandings. But a freshly fertilized rose bed and Freddie's attempts to sell dog food to the guests make the visit anything but sophisticated.

Connie insists Clarence spruce himself up for a visit by the sophisticated Lady Daphne and her spoiled brat, Huxley. But when Daphne takes an unusual interest in Clarence (and his prize pig), Connie becomes suspicious.
