Doo-sik, a gang leader's second-in-command, gets a rare opportunity to attend school as a student teacher. After failing to complete his high school course years ago, this is his chance to redeem himself. However, he views his teaching practice as a social adaptation course for soon-to-be-released prisoners, rather than a traditional teaching experience. Despite his enthusiasm, Doo-sik's eccentric behavior causes friction with the students, and things take a surprising turn when his boss, the D-Dogs leader, becomes one of his students. As Doo-sik navigates the challenges, his loyalty is tested, and he finds himself in unexpected situations.
