Moral Courage (1917)

After his son Chadwick returns home from college, factory owner Joshua Anson expects him to marry a woman of wealth. Much to his father's chagrin, Chadwick falls in love with factory girl Mary McClintock. Anson attempts to break up the romance by framing Mary in a compromising situation, but she outfoxes him and marries Chadwick. Not to be defeated, Anson offers his daughter-in-law $100,000 to divorce his son, but Mary outfoxes him once again by accepting the money, getting a divorce, and then remarrying Chadwick. Mary's last trick wins her father-in-law's respect and he finally offers the couple his blessings.
