“Like last year, the top 30 students will be given advanced classes in the school dorm.”

In Woo-sung High School, the top thirty ranking students are required to attend advanced classes from the beginning of each summer break to prepare the college entrance exam.

On their first day, the 30 students, their tutor Mr. CHA and the trainee teacher Eun-soo remain in school till midnight. Then a sudden piercing scream is heard in a silent library. At that moment, a viciously slaughtered tied up body falls from the ceiling. Soon follows the sound of a voice resonating through the school speakers.

“From this moment on there will be a test for this special class.

If you fail to find the correct answer, you will die one by one.

There are no definitions or instructions.

Only one thing is certain. Somebody must die.”

The students are thrown into a pandemonium. They try to leave the school premises but to their dismay they discover that all the exits are locked. They get into a fuss to find a way out of the school dormitories but to no avail. This situation is just impossible to escape.

In a chaos, students are terrified that the suicide girl Tae-yeon is haunting them after two years.
