The protagonist works as a taxi driver, and by chance, he saw the psychological experiment job advertisement in the newspaper and went to apply for the job. Afterwards, the actor and the other 19 people were selected as experimental subjects. Eight of them were selected as jailers and the remaining 12 were prisoners. As long as the two-week experiment is completed, each person can receive 4,000 marks as a reward. Anyone who uses force in this experiment will be immediately disqualified. In addition, the male protagonist received media remuneration for his sneak shots of experimental content.
At the beginning, everyone was in peace, talking and laughing. After that, the situation gradually got out of control, and the role of the jailer began to torture the prisoners. One of the jailers was demoted as a prisoner by the other jailers because they did not want to be in the same situation. In the end, even the researcher and female assistant who monitored the experiment were imprisoned by the out-of-control jailer. Although everyone escaped in the end, prisoner No. 82 and the supervisor in charge of the experiment were killed.
