To add a touch of English sophistication to her New Mexican estate, Effie (Lea Penman) convinces Humphrey (Bob Hope), a man she thinks is a British butler, to come to the United States in her employ. In reality, “Humphrey” is Arthur, a struggling American actor in need of a job. When Effie returns, the residents of their small town assume that “Humphrey” is the distinguished husband-to-be of Effie’s tomboy daughter, Agatha (Lucille Ball) — and Arthur is forced to play along.
