Pitfalls of Passion (1927)

Jimmy and May, young lovers, run away from their dreary farm lives to live in the city, though they don't marry. Soon Jimmy finds things aren't working out and has little ambition to work or affection for May left. In desperation he sells May into the hands of a pimp and a madam in a brothel. They don't meet again until, wounded while running from the police, he runs into a hospital ward where she's being treated for the ravages of social diseases she's accrued in the course of her degradation.
