That Girl

There Sure are a Bunch of Cards in St. Louis (1) (5x6)

:

Ann learns that killing two birds with one stone is almost too much when she goes to St. Louis with Donald to meet his parents and to star in a play. She is convinced that Don's mother hates her and decides that she might be able to turn it around if she were to have a larger, starring role in the play instead of her more modest part.
