Ellen and Mary, two sisters, are courted by George and Sam, who are brothers. At evening when the girls' mother plays to them the twilight song, she tells them that just as they are happy now in the twilight of the day, so must they watch to keep their love and happiness also in the twilight hour of life. They laugh, never doubting the future. Mary and Sam are married, and their hopes are fulfilled. George, however, goes to the city, where he goes rapidly downhill. He marries Doris Grant, and Ellen is left on the farm, broken-hearted. Years later, George, released from penitentiary, his wife dead, seeks the home of his boyhood. He finds that Sam and Mary have adopted his little girl, and faithful Ellen still is awaiting. Thus, in the twilight of life, the lovers, whose early dreams were frustrated, find their happiness together.
