Little Nan Griffing whiles away the hours on her parents' farm with Simple Simon Magee, an adult with the mind of a child. While rummaging through the attic one day, Nan discovers a costume that was worn by her mother Ethel when she was on the stage and begs to be taught to dance. Ethel complies, but the lessons are soon interrupted by several horrified members of the local church society. Next, Nan, accompanied by Simple Simon, visits her grandmother Anna and Aunt Grace in the city. Hidden in the orchard, Simon frightens the servants, who mistake him for a ghost. Nan becomes infatuated with Grace's fiancé, Morgan Thornton, and proposes, but when she steals away to his house intending to elope, Morgan summons her aunt and grandmother. Nan demands that he choose between her and Grace, and when he picks the latter, she decides to forsake city life and return to her parents.
