The series revolve around the South Korean legal system.

In South Korea, children between 10-13 are sentenced to “reformation” which aims to for rehabilitation of the child back to society. However, children between 14-18 can be punished either with reformations or official punishment such as prison terms.

The series follows the story of Shim Eun-seok, a judge of the Juvenile Court who seems to harbor a strong dislike for juvenile offenders. At first look she seems like a cold hearted person with a vendetta to punish the children with the worst ruling that could be given.

Over the course of the series, the viewer will understand that Eun-seok is the kind of judge that goes above and beyond her job requirements. She sought to understand the mind set of the offender, to understand if there was any sought of genuine regret of the crime that was committed and not just taking the words that are spoken by them at face value. She is well aware that the lawyers that take up such cases try to give the offenders a loop hole to get the minimum sentencing possible.

In the series, we get a backstory to her life which puts a light on why was she so severe towards the juvenile offenders. We also see the life of another judge by the name of Kim Mu-yeol, who seems to be the other side of the coin. He believes in second chances and always believes that children when given enough care can be better. The series gives a peep into his past as well to understand the development of his character.

The series is definitely worth a watch in my opinion. The writer certainly knows how to tap into the emotions of the viewers helping one really connect with the main characters as well as the different situations faced by the children in each of the episodes.
