Aunt Elsa, a full-of-life old lady, and her nephew, Bobby, concoct a scheme to frighten Bobby's young sisters. She puts a false face on and wraps herself in a sheet. Thus arrayed, she appears before the young ladies and badly frightens them. At a sewing bee the girls try to get even by putting on men's clothes and endeavoring to kidnap aunty, but their plan is overheard by the wily Bobby, who advises aunty of the scheme. Aunt Elsa then dresses the cook in her clothes. She is captured by the girls, bound to a tree, and as they are laughing at "aunty," the girls themselves are pounced upon by two "western desperadoes," are blindfolded and taken to a house, where they learn that they have been beaten at their own game by Bobby and aunty, who prove to be the desperadoes.
