Season 1

Dan Hyeon, a city shrouded in corruption and unsolved mysteries. Cold-hearted prosecutor Ju Tae-seon despises murderers to the core, while investigator Lee Chae-ha has spent his entire life barely surviving under the stigma of being the “son of a killer.”

On his first day after being transferred to prosecutor Tae-seon’s office, Chae-ha realizes that the case Tae-seon is pursuing is far more than an ordinary drug case.
