This is a sci-fi suspense action film about a series of thrilling events experienced by a US Air Force pilot Stevens who was on a mission in Afghanistan when he woke up and found himself on a train to Chicago.
The world of source code makes the future full of possibilities. Cherish life and treat everyone around you kindly, just like the last moment on the train in the movie, the smiling faces of people next to you are the most beautiful. Time is always the most powerful and magical category. The person who has penetrated and mastered time will become the most powerful person.
I really like the theory of parallel worlds. Just like the butterfly effect, what happened in the past will drive the development of future things. Although the hard principles of science fiction are still not well understood, I really like this interlocking plot. What happened in the past will always pass through. A series of things connect to the future and change the future.
