A string of unsolved cases dormant for ten years suddenly resurfaces. An unidentified woman’s body, bearing a mark from an old case, shatters the peace of a small town. An antisocial, stubborn forensic genius joins forces with a passionate, straightforward criminal investigation captain. As the victims’ identities gradually come to light, they uncover long-buried scandals from years ago: school bullying, workplace framing, and shadowy deals between money and power. The killer is meting out vigilante justice by extreme means, but behind the cases lies a tragic revenge spanning a decade, as well as a secret betrayal within the police force.
