Starting a new school is never easy, especially when it’s one plagued by rumours of violent murders and vengeful spirits. Unfortunately for Hui-min Lee, it takes less than two days before Yeondoo High School’s newest student finds himself trapped inside the building overnight – and thrown face-to-face with the malevolent spirits roaming the corridors.

But as soon as he stepped foot inside the shutters slammed closed for the night, locking him inside with possessed janitors hellbent on killing intruders, and vengeful ghosts eager to sap his lifeforce away.
