The Doctor's Duty(1913)

Dr. Roland White falls in love with Marguerite, the daughter of the postmaster in a small western town. He asks her to marry him, but she refuses, as she is already engaged to Fred Church, the express messenger. Some time later, after the proposal, the doctor receives an invitation to the wedding of Church and Marguerite, which shatters what little hope he had of ever winning the girl. A few days before the marriage is to take place. Church is held up and shot by bandits, and taken, in a serious condition, to Dr. White's home.
