Synopsis: A criminal profiler Park Hae-young (Lee Je-hoon), solves a kidnapping case involving a culprit who apparently disappeared after the crime, with a mysterious walkie-talkie he picks up. The success of this case triggers the formation of a long-term cold case team, led by Detective Cha Soo-hyun (Kim Hye-soo), who has been searching for her long-lost mentor Detective Lee Jae-han (Cho Jin-woong), for the past fifteen years. With the help of Jae-han, the person at the other end of the walkie-talkie, Park Hae-young solves other cold cases that have remained unsolved for years, while also helping Lee Jae-han help solve some cases in the past which results in grave unintended consequences.
