Belgian detective Hercule Poirot has to leave Istanbul for England in a hurry, but there are no more seats available on the Orient Express. His old friend Monsieur Bouc, the owner of the company that owns the train, helps him out. In the morning, while having breakfast, the detective notices that the passengers on the train are people of different nationalities who have accidentally found themselves in the same carriage. The American Ratchett, who seems too suspicious to Poirot, asks the detective to become his bodyguard. But he refuses. At night, Poirot is constantly woken up by various sounds and knocks, but then silence comes - because of snow drifts, the train stopped somewhere in Yugoslavia, the passengers are tense, and the strange Mr Ratchett lies dead in his compartment... Detective Poirot takes up the investigation.
