The story is about a man who has his daughter killed by someone and in the court, He wasn't satisfied with the law and sentence that was given by the judge. Later on, He killed the killer without knowing who's the real killer and behind all of this. In the future, there was an anonymous person who hacked the electronic device and installed an application to all people in Korea to vote about the person that he had captured along with the crime that had been committed. It's actually similar to The Devil Judge. That's where the story becomes interesting.
