A serious incident breaks out at Yeongpyeong District Construction Site, and everyone involved in Hansu Bio’s sell-off is summoned at once. While dealing with the collapse, a human skeleton is discovered, and Chan intuitively realizes that it has something to do with his sister’s death. Meanwhile, Soo Jae looks for Chan at his place, and she stumbles upon a little secret Chan has been hiding.

After finding out what Gong Chan has been hiding from Soo Jae all along, Soo Jae feels devastated and keeps a distance from him. She recollects her memories of how helpless she was when she defended Kim Dong Gu ten years ago. Meanwhile, Sung Bum pays a visit to the funeral of the victims of the construction site fall. He suddenly gets attacked by one of the bereaved family members and ends up being hospitalized.

Yoon Sang organizes a meeting in the hopes of letting Chan know the unrevealed details of his case. However, the meeting doesn’t pan out as he anticipated. Chan demands an explanation from Yoon Sang about his actions. Yoon Sang shares his reasons while having Soo Jae listen to them over the phone. Chan doesn’t know Soo Jae is listening, but his care for Soo Jae is too touching for Soo Jae to handle.

Director Baek holds a mock trial where students play the roles of judges, prosecutors, defendants, and witnesses before he resigns from university. Tae Guk is invited to the event and plays the role of the presiding judge without knowing that the case for the mock trial is very similar to the one of Na Jung’s death 10 years ago. Meanwhile, the skeleton in Yeongpyeong District gets identified. Will it be confirmed to belong to Na Jung?

Soo Jae knew about Tae Guk’s way of handling things, but when she finds out what he did to her and her daughter, she breaks down. Soon after, she gathers herself together and prepares herself for what’s to come. Meanwhile, Soo Jae cannot get rid of the feeling of intimacy between Jae Yi and herself. On her way to meet Chan to share her new secret, she gets a call saying that Jae Yi has gone missing.

After seeing her daughter die right before her eyes, Soo Jae falls into deep grief. She disappears with a letter left for Chan. Meanwhile, Tae Guk plans to disbar Soo Jae permanently. He tells the bar association to hold a disciplinary hearing and come up with every illegal action done by Soo Jae. With Jin Ki’s confirmation hearing right around the corner, he is accused of taking bribes in the past. Tae Guk promises that he will attend the hearing as a witness and defend Jin Ki.

At the disciplinary hearing, all parties claim their innocence, but no one seems to admit to their wrongdoings except for Soo Jae. On top of admitting to her wrongdoings, Soo Jae makes sure the world knows about Choi Tae Guk’s atrociousness and takes one step at a time to bring him to justice. In the battle of right against might, Soo Jae goes all in on what’s right.
