While clues proving a corruptive body’s close relation to Lee Dae Chul’s case pile up, Do Chang figures out a work-around to carry out a secret investigation on Jo Seong Dae. On top of that, Ji Hyuk hints to him how his very cousin, Oh Jong Tae, may be partially responsible for Yoon Ji Sun’s death from five years ago. Meanwhile, Dae Chul’s day of execution nears as his daughter, Eun Hye, visits him at the prison.

Do Chang confesses to Eun Hye that he wants to save her father, Lee Dae Chul. Unfortunately, Eun Hye can’t trust Do Chang who literally handcuffed and arrested her father for a murder he didn’t commit. However, Do Chang shows a sign of hope for Eun Hye by getting the re-trial approved. Meanwhile, Superintendent Moon and Yoon Sang Mi prepare themselves for the possibility of an unexpected turn of events.

Although Do Chang and Mr. So prepare for the retrial of Lee Dae Chul’s case, Do Chang still needs to persuade Dae Chul to follow his lead because he is reluctant to take part in it due to the possibility of harm that it may cause his daughter. Meanwhile, Do Chang finds himself caught in a dilemma that is inflicting harm to both the victims who lost their beloved partners and the ones who crossed the line for their greed.
