The Discarded Woman (1920)

When Martin Wells tires of his wife Esther, he boards a train with her and then deserts her. When Esther discovers that she has been "discarded," she leaves the train and comes upon the cabin of Samuel Radburn, who soon returns home drunk and attacks her. After he falls asleep, Esther escapes. Later Radburn goes to New York, searching for Martin Wells's wife to deed her half the gold mine that he held jointly with the now-deceased Wells. Radburn meets the pregnant Esther there, and believing that she is carrying his child and unaware of her true identity, he marries her. They are content until the Graeber gang, in an attempt to secure control of the Wells's mine, blackmails Esther with the threat of exposing her true identity. Esther finally confesses to Radburn, who forgives her, and all ends happily.
