You and your three friends, all of whom are men, dare to test your courage in an abandoned house that is said to be haunted. But who would have thought that the house was actually occupied by a serial killer.

When you find out about this, you and your three friends gather in one of the rooms and devise a strategy to escape from that place without the killer knowing.

While discussing, suddenly the door opened to reveal a man holding a chainsaw who was covered in blood. He, Levi Ackerman, is a serial killer.
