One fellow passenger, Samuel Ratchett, implores Mr. Poirot to assist him while on the train as he fears for his well-being, though Poirot respectfully declines.

With the train halted due to snow build up on the tracks, and with the evidence and suspects piling up, Poirot finds himself diving into a case that could be his biggest yet.
