prison classroom.

Let's start the experiment. Eleven men and women of former students who were gathered at the alumni meeting in the former homeroom will be imprisoned in the school building for three days! Men in the guard role monitor women in the prisoner role! The inmates take advantage of the situation where they can not be against the guards, and the boys attack the girls! even if you're forced to commit a crime, you have to accept that you want to escape alive... Sleep pills, numbness medications and glazes take away your body's freedom and are exposed to men! The coffin of the classmates, who were placed in a situation of limit that was chased down, gradually collapsed.
