Carolina, a melodrama directed by Henry King, follows a young woman's attempt to restore a southern plantation back to its pre-Civil War glory. Joanna Tate (Janet Gaynor), originally travels from her home in Pennsylvania to the plantation in order to collect her deceased father's belongings. Though he didn't own the plantation himself, he had worked there as a farmer for a number of years. Once she arrives, Joanna (Gaynor) finds that the actual plantation owner, Bob Connelly (Lionel Barrymore), is a Civil War veteran who, despite his dogged determination to return his farmland to what it was before the war, has fallen to alcoholism. Least expected, however, was the love that would develop between Joanna and the plantation's handsome young heir, Will Connelly (Robert Young). Joanna and Connelly (Young) eventually marry, and the farm is successfully restored through their dedication and hard work.
