Forensic Scientist Kim Junghoon lies dead in the National Forensic Service's autopsy room. He died full of regret after witnessing his work partner of 20 years, Kim Sangjin, distorted his very own autopsy report when he was still conscious and accused him of committing suicide. Right after he passed away, Kim Junghoon opened his eyes once more and found himself back in 2002 when he was still a rookie in the National Forensic Service. His final wish came true as he got himself one more chance to fix his past!
