Moral Courage (1917)

Wealthy Joshua Anson expects his son Chadwick to marry a woman of their class, but much to his chagrin Chadwick falls in love with factory girl Mary McClintock. Anson schemes to break up the romance by framing Mary in a compromising situation, but she outsmarts 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.
