Lewis (Dougray Scott) has been separated from his wife for many years. He is very busy with work and entrusts his children to his father who lives in London. Finally, Lewis got free and decided to take his father and son back to his side. He happily boarded the train to London. On the train, Lewis met a woman named Elena (Lindsay Duncan Lindsay Duncan), and the two really collided with sparks. What Lewis didn't expect was that from some point on, all the service staff in the car had lost their traces, and what was worse was that the brakes of the train seemed to have failed. It turned out that there was a terrorist hiding in the car. He tampered with the train and wanted all the passengers to be his burial objects. At present, only Lewis knows this terrible truth, and all hope is concentrated on his shoulders.
