What if a person's capacity for cruelty could be spotted before the first crime? A young police officer named Ba Reum barely survives an encounter with a killer who terrorises the country, and the meeting turns his life upside down. He starts to search for the truth about how such people are made, joined by a profiler who has his own stake in the case. The story keeps flipping what you think you know, and it is as much about right and wrong as about catching the culprit.
