The Bondage of Fear (1917)

Vesta Wheatley is the daughter of a Virginia physician; John Randolph is a New Yorker who buys a tract of land from her father. Vesta and John fall in love, get married, and move to New York. They are followed, however, by a persistent old flame of Vesta's, Dick Mortimer. He tracks her down to a mountain cabin, where she is alone. A burglar breaks in on the two, and Dick is killed trying to protect Vesta. The burglar blackmails Vesta until she finally becomes desperate and shoots him in her own home.
