Barbara Stanwyck plays Polly Fulton, rebellious daughter of a wealthy industrialist (Charles Coburn). Polly marries a conservative economist professor (Richard Hart), but she chafes at his values and leaves him for socialist professor Van Heflin. Polly nearly ruins both her father's reputation and her own by embracing Heflin's radicalism. Based on a novel by J. P. Marquand, B.F.'s Daughter emerges as an unsubtle swipe at the policies of the late president Franklin Roosevelt; perhaps this was at the behest of MGM's arch-Republican head man Louis B. Mayer. In England, where the letters "B. F." comprise a euphemism for "bloody fool", the film was retitled Polly Fulton.
