Poirot has just finished a case in Istanbul and is returning home to London onboard the luxurious Orient Express. But, the train comes to a sudden halt when a rock slide blocks the tracks ahead. And all the thrills of riding the famous train come to a halt when a man discovered dead in his compartment, stabbed nine times. The train is stranded. No one has gotten on or gotten off. That can only mean one thing: the killer is onboard, and it is up to Hercule Poirot to find him.
