In South Korean society, the school system has completely collapsed. Teachers have lost control, are being bullied, and no longer dare or are able to confront criminals and bullies in the classroom. This leads to extreme abuses such as severe assault, bullying, gambling circuits, and organized crime within school walls. In response, the government approves a new law and establishes the Educational Rights Protection Agency (ERPA). Inspectors from this agency use unconventional and harsh methods to restore order in schools.
