Connie is anxious to make a good impression on her visiting childhood friend Veronica, and her rich American husband, Jimmy Schoonmaker. She enlists the services of the pathologically fastidious secretary Rupert Baxter to purge Blandings - and in particular Clarence - who is liberally anointing his roses with stinking manure.
