In 1934, famous Belgian detective Hercule Poirot solves a theft at the Church of the Holy Sepulchre in Jerusalem. The obsessive-compulsive—who seeks balance in life, and considers his case-solving ability to see a lie amid truth to be a curse—wants to rest in Istanbul, but must return to London for another case. His friend Bouc, director of the Orient Express, offers a room aboard the train.
Businessman Edward Ratchett offers to hire Poirot as his bodyguard during the three-day journey, as Ratchett has received threatening letters from an unknown party, but Poirot refuses. That night, Poirot hears strange noises coming from Ratchett’s compartment, and later sees someone in a red kimono running down the hallway. An avalanche derails the train’s engine, stranding the passengers.
The next morning, Poirot discovers Ratchett was murdered during the night after having been stabbed a dozen times. Poirot and Bouc investigate the passengers as repairs begin. Evidence indicates that Ratchett was murdered by one person, and Caroline Hubbard, a fellow passenger, claims that a man had been in her compartment in the night. Poirot discovers a partially burned note connecting Ratchett to the kidnapping of Daisy Armstrong, a child who was abducted from her bedroom and held for ransom. After the ransom was paid, Daisy was found murdered. Ratchett’s true identity is revealed: he was John Cassetti, Daisy’s kidnapper and murderer. Her death caused her mother Sonia to die after giving premature birth to a stillborn baby; her father, Colonel Armstrong, then committed suicide. The family’s nursemaid Susanne was arrested and hanged herself while in police custody, but was posthumously exonerated.
