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.

It was already difficult enough for Do Chang and others to get a retrial approved. However, feeling desperate during the trial, Dae Chul falsely admits to his killing of Detective Jang Jin Soo. Meanwhile, Seo Gyeong receives a recording from an unknown sender of a conversation between Superintendent Moon and a prosecutor, which could act as solid evidence to prove Dae Chul’s innocence.
