Know Your Men (1921)

Warren Schuyler, a wealthy widower in a small Eastern town, is highly-respected until the citizens are financially ruined by devaluation of the oil stock he sold them. His daughter Ellen's New York socialite fiance' Roy Phelps deserts her after her father dies, but fellow townsman John Barrett comes to her aid, and she marries him out of gratitude. After three years of irritation from her mother-in-law, she again meets Roy and is persuaded to leave her husband and child, but on perceiving Roy's fraudulence, and following a serious illness, she reunites with John.
