Teach You a Lesson

"Teach You a Lesson" is an action-packed Korean drama set to deliver sharp lessons on authority, discipline, and justice in the education system.

Overview

"Teach You a Lesson" (native title: 참교육, also known as "True Education" or "Get Schooled") is a South Korean action school drama series. Directed by Hong Jong-chan and written by Lee Nam-kyu along with others, it is based on the popular Naver webtoon of the same name by Chae Yong-taek and Han Ga-ram. The series explores the collapse of teachers' authority in schools amid rising student delinquency, parental pressures, and systemic failures. In response, the government establishes the Educational Rights Protection Bureau (ERPB or ERPA), a task force with special authority to intervene decisively.

The 10-episode series blends action, thriller, comedy, and social commentary, promising cathartic moments as its protagonists tackle school chaos with unconventional methods. It is scheduled to premiere on Netflix on June 5, 2026.

Plot Synopsis

School violence, unruly students, demanding parents, and weakened teacher authority have created a crisis in the education system. To address this, the National Assembly passes the Teacher Rights Protection Act, leading to the creation of the Educational Rights Protection Bureau. This new government organization grants its agents legal immunity to use physical intervention and other strong measures when necessary.

Na Hwa-jin, a dedicated supervisor from the bureau, is dispatched to problem schools. Working alongside his team, he confronts delinquent student hierarchies, administrative corruption, and various threats to restore order and protect victims. The story follows their high-stakes missions filled with intense action, clever strategies, and bold confrontations.
