Lin En, a soon-to-be college student, suddenly finds himself trapped every night in an inescapable dream of eternal darkness, where terrifying monsters roam everywhere.

He thinks he has escaped fate and risen above the darkness.
Only at the very end does he realize the truth: the one hunting monsters is becoming a monster himself.
