A young university student Baek Ji-eun gets kidnapped and killed. The investigating detective is Sung-jun and the judge of this case also happens to be his brother, Sung-hoon. Although Sung-jun finds a suspect, the court is not sure whether he is the real culprit or not. As the trial proceeds with a jury, the case draws a lot of attention.

The jury reaches a verdict that Man-chun is guilty and is sentenced to a lifetime in prison. Just when everyone believes that it is now over, Man-chun manages to escape from his convoy and searches for the jurors to seek revenge. However, his vengeance fails and the truth behind the Joker Murder reveals itself.

Sung-jun wakes up after getting hurt from the hostage situation. But the only things that greet him are his parents’ nagging and the news of another woman’s death. While the public believes the second murder is done by a copycat killer, Sung-hoon gets a hunch that Man-chun is innocent and that there truly is someone else behind the Joker cases.

The jurors are being targeted as the Joker murderer’s victims. As Ki-nam and Moon-kang learn that the cases are related to Hope Welfare, they collect evidence to find their daughters’ killer. Eventually, their investigation leads to the idea that Ryu Sung-jun might be Jung Yoon-jae. Believing this as a fact, Moon-kang kidnaps Sung-jun.

Sung Jun manages to escape from Moon Kang thanks to Eun Ki. As she believes that Sung Jun is not the killer of the Joker Murders, she helps him clear his name. However, the public and the police are certain that he is the culprit. Being chased by his own colleagues, he must prove that he did not kill anyone.

Sung Hoon believes that Sung Jun is not the culprit. Not because they are brothers, but because the current evidence is not enough, and that new evidence starts emerging. Kwon Yu Na gets attacked by Choi Soon Gil. As he is one of the suspects in Yeom Hye Jin’s murder, Sung Jun begins digging into him deeper.
