“Trapped in a murderer's body”

Two years after a serial killer murdered his colleague and brother-in-law, homicide detective Jae-hwan (Oh Dae-hwan) finally has the man in front of him. Then, in the middle of the chase, both of them are caught in an accident, and Jae-hwan comes to in a hospital bed inside the killer's body. Kim Jae-hoon puts Jin-hyuk (Jang Dong-yoon) on the other side of the switch, wearing the detective's face.
