When the thick fog rolls in, no living soul should venture outside.
Eight ordinary people who stumble into a desperate situation are forced to enter one forbidden death zone after another.
Searching for bones in a deserted village, retrieving a boat at a ferry crossing, listening to opera in a haunted town, walking the coffin mountain at night…
Every place they stay hides ironclad rules: break one, and you die.
Something waits outside the door for you to turn around. Someone beneath the bed listens to you breathe. Eyes watch you from every corner of the dark.
No System. No supernatural powers. No way out.
Suspicion, fear, sacrifice, betrayal.
They flee from one place to the next, only to realize at last:
The fog is no natural disaster. It's a hunt.
Their lodgings are no refuge. They're cages.
They aren't survivors. They're the final living sacrifices, kept like livestock.
The fog will never lift. The night will never end.
Who will die next?
