Mr. and Mrs. Willis and two daughters live contentedly. The older girl Lillian is engaged to a young man who, after asking her hand in marriage of her parents, leaves for the city. Sometime later the mother, who is an invalid, dies, and leaves the younger girl as a sacred charge to Lillian. The young man returns from the city, but Lillian will not marry him, telling him that her duty is with her father and sister. He leaves despondent. Years later May, the younger sister, has grown to womanhood, and they walk to the last resting place of their mother and father. May has a sweetheart, and he asks the elder sister for her hand in marriage. She consents, on the condition that they will make their home with her and they do so. Two years later May is the mother of a lovely baby, and her life is very happy, while Lillian by the fireside, dreams of what might have been. In the city, her girlhood lover dreams, too, and of her. One evening, Lillian is sitting out in the yard, and in the house, the younger sister is singing a lullaby to her baby. The light shines from the open window on her face, showing a longing infinitely sad. To her side comes the girlhood lover from the city, and he too, sees the picture over her shoulder. When Lillian turns, she finds herself in the arms of the man she has loved through years.
