10 years has past since Choi Jung-joo was caught stealing her brother’s case files and she has become a Judge under the name of Lee Jung-joo. When her current trial case files are snatched by a thief, her job is placed in a precarious position. Matters get worse when she can’t control her fiery temper against convict Kim Joo-hyeong who attempts to lay the blame on the victims. Judge Sa Ui-Hyun’s theft case goes awry when the defendant injures herself.

Judge Lee Jung-joo retrieves her lost case file from Judge Sa Ui-hyun and their personalities initially clash with each other. Things go drastically wrong during the Kim Joo-yeong retrial case when the court record is taken hostage. Her refusal to acquit his case causes Joo-yeong to “educate” Jung-joo.

Caught in an unprecented hostage drama, Judge Lee Jung-joo is trapped with no way out until Judge Sa Ui-hyun attempts to assist her. While deliberating on whether to take the Jung Soon-bok case or transfer it to another judicial panel, Professor Yoo Myung-hee, her idol, provides Jung-joo with the insight to make her decision.

Judge Lee takes the Jung Soon-bok case. Choi Kyung-ho assaults Kim Joo-hyeong in prison for what he did to Jung-joo. When brought before the court, he reveals that he lied about raping and murdering Kim Ga-young. Assemblyman Do Jin-myung reveals to Sa Jung-do that Seo Ge-ho, the husband of Soon-bok, found out Kyung-ho did not murder Kim Ga-young.

The court is in turmoil due to the unexpected bombshell declaration by Choi Kung-ho. Lee Jung-joo’s feelings are complicated because she always believed that he had committed the crime. Sa Ui-hyeon is made aware of the fact that the tennis shoe Kim Ga-young wore when she was murdered had belonged to Do Hoon-joon. Assemblyman Do Jin-myung knows more than what he is telling.
