A British actor attempts to impress two visiting American women, Efflie Floud and her tomboyish daughter, Agatha, by having the cast of his drawing-room comedy pose as his aristocratic family. Effie persuades the 'butler', Humphrey, really a struggling American actor named Arthur Tyler, to accompany them to the United States and help to refine both her husband and daughter. She sends a telegram home, referring to the person she believes is Humphrey as a "gentleman's gentleman", which the rural western townfolk misunderstand as meaning he is an aristocrat and presumably the future husband of Agatha. Arthur must now pretend to the family that he is this British butler while pretending to the rest of the town, and the visiting PresidentTheodore Roosevelt that he is a politically savvy Englishman.
The deception is eventually uncovered, and the actor and the family's daughter gradually fall in love.
