Miss Deception (1917)

When Joyce Kingston, who has been living in the Kentucky hills with her Uncle Ed, is summoned to her father's city home, she learns that her high toned family believes that her years of country living have rendered her a hick, and so, not wanting to disappoint them she decides to play the role of a country bumpkin. Although finely educated and a stickler on etiquette in her uncle's home, Joyce pretends to be illiterate and offends everyone with her crudeness. Joyce's antics alienate her father's fortune-hunting fiancé Genevieve, who thinks that Joyce is a barbarian. Believing that Kingston is about to lose his wealth, Genevieve breaks her engagement, and Joyce's happiness is made complete when her sweetheart sees through her bumpkin act and proposes marriage.
