Internationally famous private detective Hercule Poirot is on his way back to England after solving a mystery in Syria. He decides to take the Orient Express for part of his journey, only to discover that despite the train normally being quite empty during the winter season, it’s so fully booked in first class that he has to stay the first night in a second class cabin. Poirot is approached by one of the passengers, a Mr. Edward Ratchett, who claims he has many enemies and that his life is in danger. He wants to hire Poirot to protect him. The little Belgian detective turns him down.
The second night on the train, when Poirot has been moved into a first class cabin, there are several strange occurrences, and in the morning, the passengers discover that not only has the train stopped entirely, due to large amounts of snow on the tracks, but Edward Ratchett has been murdered during the night. No one could have got onto or off the train, so one of the passengers is the likely culprit. Poirot is tasked with identifying the murderer before the train starts up again and the guilty party can escape.
