Two rival high school gang leaders square off in Bangkok over honor, school pride, a girlfriend and rock-n-roll popularity.

During school break, there was a rule that students must leave their school dormitories to return home. However, a group of students who love to visit haunted places to challenge ghosts, gathers their gang for another trial. Their place of choice was the Daeng Building, which has a history of being one student’s tragic suicide spot. After the suicide, the building was abandoned and became restricted to all students. Without thinking twice, the group decides to explore the place and challenge the supernatural beings there to “make them shudder”, which leads to a chain of unforgettable and horrifying events.
