Do-han teve sua suspensão levantada e é chamado para uma cena de crime de assassinato por Jong-hun. Ao chegar no local, ele encontra o corpo morto de Song Young-jin, o cúmplice do maior caso de fraude do século, o esquema Ponzi No Sang-cheon. Ele também encontra vestígios de No Sang-cheon, que morreu há oito anos.

Enquanto ele mantém a vigilância sobre o suspeito Byeong-jun, Do-han suspeita que o caso está relacionado à organização de vítimas de fraude de No Sang-cheon. Então ocorre o segundo assassinato, em que a vítima relata à polícia que No Sang-cheon está tentando matá-lo. Na cena do segundo caso de assassinato, Do-han se reencontra com Byeong-jun e reexamina o caso como um assassinato em série.

As Do-han tries to release Byeong-jun having no clear evidence, Byeong-jun suddenly confesses to the murders. Meanwhile, Na-yeon prepares for a press release about the serial murder cases, and Jong-hun hears surprising news from Byeong-jun when he visits him at the Prosecutor's Office.

Jong-hun looks into the past BIGS Network investigation files and finds out that the unreleased first murder victim was So-ram. Meanwhile, Na-yeon is prevented from releasing any articles regarding the case, so she reveals to Do-han that the murder victims are dying in the order on Jae-hwang's list.

Jong-hun, tormented by the impending doom that is written on the list, disappears. Do-han manages to find where the new suspect Jae-hwang had been staying after his release, but encounters Jae-hwang in an unexpected situation.

Jong-hun says that he was abducted by Jae-hwang, and the case seems to come to a close with suspect Jae-hwang's death. However, as Na-yeon and the victims' group receive another murder message, everything falls into chaos.

After learning of Da-jeong's investment briefing, Do-han makes a visit and witnesses a shocking scene. Meanwhile, Jong-hun vows not to cover up anything any longer and starts to delve into the case. In doing so, he tells Do-han the truth about the night of his abduction.

Determined not to repeat his mistakes, Jong-hun looks back at his shameful past and reinvestigates the No Sang-cheon fraud case. In the process, he unexpectedly runs into the ones that helped No Sang-cheon flee previously.
