Lin Mo enters an apartment building cursed at midnight. Whenever the hallway phone rings, it claims a life, and a ghostly shadow lurks in the mirror, able to imitate anything.
Deadly taboos, one fatal trap after another, and dark truths are steadily revealed. Through countless nights, he clings to the rules, fights evil spirits, and searches for a way out.
The ringing never stops, and neither does the curse.
Making it to dawn is the only hope of survival.
