Dr. Finlay survived World War II and now in the aftermath has been serving in the Royal Army Medical Corps. He returns to the small town of Tannochbrae in Scotland expecting to resume life as it was.

His fiancee has decided not to wait for him, he must deal with new colleagues and even the arrangements of the practice are overturned as the resolutely chaste housekeeper is wooed by the local chemist.
