The Seventh Commandment (1932)

David is a young country hick who leaves his small hometown to seek fame and fortune in the city. He falls in with rough companions, who introduce him to nights of bawdy revelry in which ladies play strip poker, men dress as chorus girls, and sexual orgies take place on the floor. Disgusted with this life, David decides to return to his hometown to marry his childhood sweetheart, Mary. But David has contracted syphilis, and he seeks medical attention, but the quack doctor bleeds him for money. When David protests, the doctor shows him a photograph of diseased genitals. Some time later, Mary is taken to the hospital to give birth to their child, but must undergo a Caesarean section because she too has contracted the disease.
