Sis is a country girl, but being left a large sum of money, she goes to the city to visit her cousin Alice. At first she is gawky and awkward, but after a few months, Alice and Clarke make a beautiful and talented girl of her. She meets a young man named Boyd, an intimate friend of Clarke's, and the two immediately fall in love. In the meantime Sis's aunt and uncle in the country become homesick to see her and decide upon a visit to the city. When they see her beautiful home and her still more beautiful clothes, they realize the gulf that has grown between them and return home heart-broken at not seeing the little girl, who had left them. Sis learns of their disappointment through a letter they send her, reading between the lines the reasons of the old couple's chagrin. She plans a surprise. Dressing up in her old gingham dress, which she had worn when she came to the city with Boyd, Alice and Clarke, she goes to the country to see the old folks. Her aunt and uncle are delighted to see Sis once more as she was before she went away, and their happiness is complete when Sis tells them, "I will be Sis to you always."
