Seized with a fainting spell during a polo game, Donald Van Wye is given six months to live and told he must go to Arizona. His brother Tom, an irresponsible college youth, is wired to come home and take Donald's place. When Tom arrives, Donald finds that his little brother has committed himself to an actress named Maizie. Donald pleads with the actress to give Tom up, but when she refuses, Donald marries her in order to save his brother. The couple go to Arizona where their love ripens, and through Maizie's prayers, Donald regains his health. Mrs. Van Wye then comes to visit and tells Maizie that she is preventing Donald from assuming his rightful place in society. Crushed, Maizie starts across the desert alone, and when Donald learns of his mother's dreadful behavior, he follows Maizie and begs her to stay.
