The plot and title of Unwed Mother are virtually one and the same. Betty (Norma Moore), the heroine, falls for the smooth line of patter delivered by no-good heel Dona (Robert Vaughan). Pretending to be a man of wealth, Dona convinces country gal Betty to give him her paychecks, promising to pay her back as soon as his inheritance comes through. He also assures her that he'll marry her when the time is right. When Betty becomes pregnant, she learns what the audience has known all along about the prevaricating Dona. After putting her child up for adoption, Betty has second thoughts, and thus spends the final reel chasing after the foster parents who've taken charge of her baby. Unwed Mother was originally released on a double bill with the equally unsubtle Joy Ride.
