Genevieve Rutherford Hale, a pampered youngest child, reads an advertisement for women to work on farms to increase food production during World War I. After having her modiste make silk overalls which Genevieve models on Russian ballet attire, she arrives at the Hubbard ranch in New York State with her chauffeur, maid, and pet dog, to be a "farmerette." While Genevieve finds the chores difficult and the other girls unfriendly, the youngest Hubbard child, Bobbie discovers officer training camp to be equally discouraging. Although he is tempted to desert, Bobbie only leaves for one night to see his home again. He finds Genevieve crying in a potato patch, and together they resolve to do their patriotic duty. When a prying neighbor, seeing them together, tells the Hubbards that Genevieve was with a soldier, Genevieve remains silent about Bobbie's identity, and is banished from the ranch. After Bobbie gets a furlough and explains matters, the Hubbards apologize to Genevieve. Bobby proposes, and they plan to marry when he returns from "over there."
