Plot:1One day in August, 938, Miss Kelly, an American, rushed to London to get married. Mr. Kant, photojournalist of Life magazine; Mrs. Frey, who worked as a nanny for a German general, has now resigned and returned to her hometown. Chatez and Mr. Court who went to London to watch the international cricket match; Dr. Harritz, like a scholar, boarded the train to Basel at a small station in Bavaria called Dosa.

After getting on the bus, Miss Kelly and Mrs. Frey were lucky enough to sit in the same box with the client who claimed to be the Baroness of Germany. Shortly after the train left, something strange happened. When Kelly took a nap and opened her eyes again, she found that Mrs. Frey sitting opposite had disappeared. I asked everyone on the train, including the baroness, and the result was that she had never seen anyone like Fury. Kelly thought there must be a ghost in it.

When the train passed a small station, Dr. Hariz got off the train and carried a patient with tight gauze on his face to his box. Just when Kelly was a little impatient because she couldn't find Fury, others mistakenly thought that Kelly was in a trance after drinking. A trademark pattern floating from the front of the window made Kant realize that Kelly was telling the truth. In the process of searching for Frey with Kant, a pair of high heels worn by the nun who was in charge of taking care of Dr. Hariz aroused Kelly's suspicion about Hariz and the patient who was masked with gauze. At this time, Kelly and Kant drank the red wine that Hariz drugged, and Hariz admitted the fact that the patient was furious.

It turned out that Hariz was a stubborn Nazi, and Frey returned to London with a great secret concerning the survival of the country. After a life-and-death and thrilling contest, Kelly and Kant saved Frey and successfully drove the train surrounded by German Nazis to the territory of neutral Switzerland. When Kelly and Kant, who loved each other, rushed to the London government to hand over the secret telegram Daphne confessed before getting off the bus, to their surprise, they saw Mrs. Frey who mysteriously disappeared on the train in the office building of the London government.
