禁闭鬼校

Yoo-ra, who suffers from nightmares every night, reunites with her high school friends including the promising artist Jin-tae, the chaebol and former thug In-seok, Hye-jin who has feelings for In-seok, and Seong-ho, once In-seok's errand boy. When Yoo-ra asks if they remember the classmate who committed suicide, everyone becomes flustered and denies it. After passing out in the bathroom upon seeing herself in the mirror, Yoo-ra and her friends head towards her home but end up in a car accident. They all become unconscious and when they regain consciousness, they find themselves in their old closed-down school, trembling in fear for their lives, wondering why they are there.
