This is mainly the story of a doctor in his efforts to help his patient, Cynthia.The reasons why he do this are unclear, and this is what the movie is all about. Also, the telephone scene with Mr. Selkirk and Dr. Lee is just hilarious. The story is important, too, because it points out how a serious illness can be misdiagnosed -although things have changed a lot since 1947, it could still happen.
