Kansas, 1910. Widowed farmer Jacob Witting finds that taking care of both his farm and two children, Anna and Caleb, is too difficult to handle alone. John takes out an ad in a newspaper for a mail-order bride, to which the “plain and tall” Sarah Wheaton answers, soon traveling from Maine to Kansas to become John’s wife. Despite the love that grows between Sarah and the family, Sarah finds herself homesick, and she must ultimately choose whether or not to stay.
