When imperious American widow Beatice Chavender eats a forkful of inferior ham at her sister's country home near London, it affects the lives of everyone around her--her sister, her brother-in-law, her sister's butler, her sister's poor relation Sally, Sally's fiance Lord Holbeton, and, most of all, Mrs. Chavender's own one-time fiance, "Ham King" J.B. Duff, whose rotten product spoils her breakfast.
