Margaret, the Mutual Girl, who has lived within the narrow confines of a farm house, receives a letter from her aunt in New York, a wealthy society woman and member of the best sets, to give up the life as a dairy maid and make her home in the great metropolis. While Margaret is enthusiastic over the prospect, she is nevertheless sorry to leave her country sweetheart, but is induced to do so when a picture of grandeur, beautiful clothes and good times is presented to her. She comes to New York and, unknown to her, is followed by her country boy lover. Her aunt meets her at the Pennsylvania Station and realizes immediately that Margaret must undergo a certain amount of training for the society life that she has mapped out. She is whisked to the home of her aunt in Fifth Avenue in a limousine car and the next day is taken on a shopping tour, where visits are made to the parlors of famous modistes and equally famous shops and department stores until the girl’s personal outfit is a liberal education in up-to-date dresses in all its multitudinous details. While this is going on the country boy arrives in New York and goes through a series of humorous scenes in trying to find a place to live and work to the winning of his sweetheart.
