Jin-woo awakens after being in a coma for a year, to find that Kyeong-hee and the rest of the team are trying to track down a kidnapper of handicap people.
As Jin-woo tries to forgive Kyeong-hee for asking In-gak to operate on him, the team investigates the murder of a policewoman who had reopened a rape case.
The team receives a new member, Han Shi-wu, while investigating on the supposed suicide of a famous dancer. Kyeong-hee runs into her old high school boyfriend.
Jin-woo goes undercover, as an office worker for a local company, in order to look deeper into the cause of death of one of the employees. Kyeong-hee looks deeper into Jae-joon's secret case.
Shi-wu's abduction takes a backseat as attentions converge on pulling elements of the season-long mystery together, starting with bizarre revelations for Jin-woo.
Without proof to bring down the irredeemable criminals legally, the team resorts to dirty tactics in a last ditch, caution-to-the-winds effort to rid the world of them.
