Crusty Dr. McRory (Barry Fitzgerald) of Fallbridge, Maine, hires a replacement for his vacation sight unseen. Alas, he and young singing doctor Jim Pearson (Bing Crosby) don't hit it off, but Pearson is delighted to stay, once he meets teacher Trudy Mason (Joan Caulfield). The locals, taking their cue from McRory, cold-shoulder Pearson, especially Trudy's stuffy fiancée. But then, guess who needs an emergency appendectomy.
