Created by Byun Young-joo
The premise
Cha Su-yeol, a police officer who has long despised his mother, the notorious 'Mantis' serial killer, must reluctantly turn to her for help when a copycat killer emerges.
Horror Vault's take
When a copycat killer surfaces, mimicking the methods of one of Korea's most feared serial murderers, a detective finds himself forced into the last alliance he ever wanted — with the monster who raised him. Ko Hyun-jung leads as the imprisoned 'Mantis,' whose chilling intellect becomes an unwilling weapon against an equally dangerous predator. The series digs deep into the psychological scars that bind hunter and hunted across generations, blurring the line between protector and predator. Fans of slow-burn Korean crime drama with a deeply personal horror edge will find much to savour here.
