What is Daughter of Mine about?
Rosie Mendelsohn, the daughter of a kindly Jewish tailor in New York City's East Side ghetto, ends her romance with struggling author George Howard at the behest of her father, who prohibits her marriage to a gentile. George disappears from her life, and Rosie attempts to find him by becoming a private secretary to publisher Joseph Rayberg. She persuades Rayberg to host a contest in which authors submit endings to an unfinished manuscript she claims to have discovered. Rayberg, intent on seducing Rosie, agrees to publish the manuscript only after Rosie promises to have sex him when the contest is over. In reality, the manuscript is a portion of George's novel, a humorous story based on Rosie's life. After receiving George's ending to the story, Rayberg locks Rosie in his office, but she escapes into George's arms. Her father relents and blesses their union.
