Private Number is the old saw about the wealthy young man who marries his family's serving girl. This time Richard Winfield (Robert Taylor) is the handsome, aristocrat hero, while Ellen Neal (Loretta Young) is the gorgeous, low-born heroine. Though they oppose the match, Richard's parents cope with the situation as best they can, but arrogant family butler Wroxton (Basil Rathbone) works overtime to break up the happy couple. Wroxton, of course, is not entirely motivated by snobbery -- he has a craving for Ellen himself. Private Number is based on Cleave Kinkead's stage play Common Clay, previously filmed twice under that title.
