The Netflix series follows the story of Yeon Si-eun (Park Ji-hoon), a student who focuses solely on himself and his studies. He ends up losing the friends he once fought alongside against school violence. Riddled with trauma, he transfers to a new school, only to come face to face with even greater violence.
At Eunjang High School, Si-eun meets a new set of friends — Park Hu-min (Ryeo Un), Seo Jun-tae (Choi Min Yeong), and Go Hyun-tak (Lee Min Jae) — and foes like Choi Hyo-man (Yu Su Bin), Na Baek-jin (Bae Na Ra), and Geum Seong-je (Lee Jun Young).
Director You Su Min and executive producer Han Jun Hee once again deliver a compelling series with a powerful young cast, exploring the darker side of teenage life and how these students stand up for one another.
