Enter Locker -- his polar opposite and his enemy. When Locker uses her ability to ‘lock’ a witness and prevents Kim from accessing key information in a crucial case, they plunge into a cat-and-mouse game with justice itself at stake. When two equal forces collide, who will emerge the victor? (Source: WEBTOON)
