This is a horror story about a classroom at the end of the classroom building. Because of a previous murder, it is said that the soul cannot be liberated, which causes strange noises in that classroom. Meanwhile the murderer is still on the loose. On one occasion, four students stayed in school to complete their homework because of their heavy workload. They encountered strange things one after another. They also played the 4-corner game to summon ghosts, which eventually led to their death.

这是一个关于教学楼尽头的一间教室的恐怖故事。据说因为之前的一起凶杀案，灵魂无法得到解脱，导致教室里怪声不断。与此同时，凶手仍然逍遥法外。有一次，四名学生因为课业负担太重而留在学校完成作业。他们接二连三地遇到怪事。他们还玩了召唤鬼魂的四角游戏，最终导致死亡。
