At an exclusive high school in Seoul, examination marks matter and so do parents' social status. To prepare for a visit from students from England, two popular teachers, Mr. Kim and Ms. Choi, gather top pupils for a Saturday study session. Things go awry: one by one, students disappear, dying in grisly ways, sometimes in view of the others via closed circuit TV. A voice on the P.A. system warns of death if anyone tries to leave. The voice also asks questions, and Mr. Kim leads the students in trying to solve them, hoping to save a student. Will the ordeal come to an end, and is the cause rational or supernatural? What's the pattern? 故事的真相。伟大的考试制度。关于韩国恐怖片的基本模式。請你一定要看完最後十分鐘！。考·死。校园：微型社会所隐藏的阴暗面。满分的剧本，只可惜拍出了五十分的效果!。魔由心生。死亡、知识与生存的交织。人生的考试永无终结。
