It is said that only the dead can board an endless train.
Wealth, revenge, immortality, the resurrection of a loved one - as long as you survive enough platforms, the train can grant any wish.
College student Bai Yujing died in a car accident and became a passenger on the A749 train when he woke up. What awaits him is a closed carriage hiding a dummy, a rainy night platform that swallows memories, a reflection in the mirror that can replace the real body, and a group of fellow travelers who may betray each other at any time for their wishes.
The violent special operations team, the cold-blooded surgeon, the national security police who are tracing the truth behind his death, the mysterious hacker who wants to completely disappear from the world...
None of them is absolutely good, and none of them is truly innocent.
The train doesn't care about good or evil, it only cares about transactions.
But when your wish finally comes true, can you still be sure that you will still be the one who lives to the end?
