Thirteen years old Luhan seemed to have this dying curiousity of his neighbor, Mrs. Lee, the lady in her sixties who always seemed to be reserved, and, evil. Boasting to three of his friends - Jongin, Kyungsoo, and Sehun - about a headless ghost that frequently appeared in the front of her house, Luhan was successful in making them drop dead curious and trick them to accompany him getting into his big plan. The three of them were cunningly trapped, wanting to prove all the bull their friend talked since they didn't believe in ghost, at all.

One night, they had a sleepover in Luhan's place and planned to take a peek into Mrs. Lee's residence to witness the ghost by their own eyes. However, Luhan's agenda was not only the sightseeing. He made them sneak into the house, facing the infamosly horrifying Mrs. Lee and finding out what had really happened with the people who misteriously disappeared after being invited into her house.

Would Luhan, Jonging, Kyungsoo, and Sehun be able to escape from the house safely?
