The Miracle Woman (1931)

Florence Fallon (Barbara Stanwyck) is outraged when her minister father is fired after many years of selfless service to make way for a younger man. She tells the congregation what she thinks of their ingratitude. Her bitter, impassioned speech impresses Bob Hornsby (Sam Hardy), who convinces her to become a phony preacher for the donations they can squeeze out of gullible believers. She builds up a devoted national following. Then she meets a blind John Carson (David Manners), falls in love, and the sham comes tumbling down.
