Others work the night shift to save their wages, but Lu Chen works the night shift to save his life.
After being laid off, he became a night shift property manager in a CBD office building. After midnight, the elevator will light up a non-existent floor. The floors are full of people who are still working overtime, but those things are not people at all.
Lu Chen is the only one who can see the rules in advance. But the rules are changing every night, and this building is not satisfied with just one more floor. If he can't stop it, this building won't be the only one that loses control.
