Madonna of Avenue A (1929)

"The beautiful Dolores Costello talks again!"

A young woman is shocked to discover that her mother, who she always believed was a stylish and successful member of upper-crust society, is actually a dance-hall "hostess" at a low-class nightclub. Wanting revenge on her mother, she marries a brutal bootlegger, which causes her mother to do something that turns out to have dire consequences for everybody. This is reportedly a lost film.
