The Devil Judge

After two years of turmoil brought on by an unidentifiable disease that dramatically comes to an end, the government plans to hold an experimental trial where the people are the judges. Kang Yo Han, the presiding judge of the experiment, is known for his unforgiving ways of justice. However, is justice what he genuinely intends? The newly appointed presiding judge, Associate Judge Kim Ga On, starts to suspect Judge Kang, whom he admires.

Judge Kang Yo Han yawns as a victim weeps in front of him. As everyone applauds him for his sentence, Judge Kim Ga On's distrust in him deepens. Although Judge Kang senses Ga On's skepticism, he still invites him into his dazzling world. A tug of war between the enigmatic Kang Yo Han and the mystified Kim Ga On begins.

An explosion in a judge's office shocks the entire nation. Was this an act of terror, or was it someone's warning message to Yo Han? However, Yo Han continues to race towards justice. What is the next trial he has prepared? Meanwhile, Ga On, who had lost consciousness while saving Yo Han, wakes up in a quiet mansion.

With new information, Ga On falls deeper into confusion. He and Soo Hyun investigate Yo Han's past, and Lee Young Min fails to stop the indictment against him. Meanwhile, Cha Kyung Hee gets engulfed with anger against Yo Han and tries to figure out how to save her son.

Ga On returns and starts working with Yo Han and Jin Joo again. His fans and the public welcome his comeback. Kyung Hee secretly visits his son in prison and watches him in grave pain. Then, Sun Ah comes up with a new strategy for Kyung Hee to tackle the situation. Meanwhile, a famous actor who has a young daughter is accused of committing sexual violence against his female colleagues, and the live trial starts.

Ga On introduces Elijah to Soo Hyun, but this makes Yo Han furious. Yo Han strongly warns Ga On not to do anything to Elijah. Kyung Hee holds a press conference and claims that Yo Han bribed a witness who made a testimony on his first live court show. The public gets deeply disappointed by Yo Han. Meanwhile, Soo Hyun gets attacked while following a witness of the Joo Il Do case.

Yo Han declares war against the state as he admits to his crimes in front of the people. The people of power at the foundation are outraged at Yo Han's surprise attack. But strangely, Sun Ah remains calm as if she had anticipated it. What does Sun Ah have up her sleeve? Meanwhile, Ga On reminds Yo Han, who has lost all faith in the world, of the importance of justice, as Yo Han takes him somewhere.

Ga On gets shocked after realizing the prisoner isn't the man he remembers. And for the first time, Yo Han candidly reveals the hardships of his life to Ga On. All the beliefs and morals Ga On has lived by crash down on him as he experiences firsthand the corruption of those in power. Now, he slowly recognizes his developing sympathy toward Yo Han. Will Ga On take Yo Han's hand against the recklessness of those in power and stop them?

Yo Han is like a hyena playing with its prey while Sun Ah hovers around the live court show. Sun Ah's presence disturbs him. But for some strange reason, he notices the loneliness hidden in the smiling face she shows him. What is the definition of the relationship between them? Meanwhile, Ga On determines to stand by Yo Han, who he thought was evil, and together, they go after the people of power, the truly evil ones.

An immense figure stands hidden behind Juk Chang, the YouTube star who was only considered to be attention-grabbing. Shocked by this new information, Yo Han and Ga On decided to put Juk Chang on trial in the live court. However, it's not an easy task with the police protecting Juk Chang. With the help of Soo Hyun, they start their hunt for Juk Chang.
