Kang Yo Han (Ji Sung) is the “Devil Judge” – the head judge of the highest court in the land. In a dystopian South Korea of the future, his word is the law, but his courtroom is also a television studio, and the court has become the ultimate TV reality show, with viewers invited to participate in a live, self-styled “people’s court.” Here, greed and corruption are apparently exposed for all the nation to see, and punishments meted out accordingly. A divisive figure, the public is unsure as to whether Kang Yo Han is a true popular hero or a malicious force sowing the seeds of chaos in his court. Meanwhile, Jung Sun Ah (Kim Min Jung) is a tough, intelligent, and ambitious woman with a hunger for power. She has formed a bitter rivalry with Kang Yo Han and has risen from poverty to become the director of a corporate social responsibility foundation. She wields considerable behind-the-scenes power, maintaining close ties with politicians and business leaders alike – and is hellbent on promoting her own vision of the future. She is also gunning for the “Devil Judge” himself – hopeful of uncovering her rival’s darkest secrets. Into this turbulent world step two childhood friends on a quest for true justice: a rookie orphan judge called Kim Ga On (Jinyoung) and a police officer named Yoon Soo Hyun (Park Gyu Young). Do they have what it takes to take on the scheming Jung Sun Ah...and the “Devil Judge?” “The Devil Judge” is a 2021 South Korean drama series that was directed by Choi Jung Gyu.
