[1][2] July 16, 1988 a night train (or "red eye") to Yeosu leaves Seoul station and crashes killing 250 people.

A stewardess named OH Mi-sun (Jang Shin-young) has just started the job and is working on said train.

Mi-sun has psychic powers that were previously unknown to her, and starts getting glimpses of the spirits of those who died in the crash fifteen years prior.

As the trains, natural and supernatural begin to part, things start getting back to normal on the train with the ghosts disassembling, the old carriages becoming normal again and the human passengers start coming out of hiding.

The white end titles are rolled up against a night background that a driver would see from the cabin of the train.
