Although she spends most of her time with petty criminals, she has to pay the debt of her family and speaks often harshly, but inside she has a golden heart. Meanwhile, Lee Dong Joon (Lee Sang Yoon) is a righteous elite judge, brilliant in mind, but with a warm heart. He always has a friendly ear for those who are weak. Both work together to solve a case of corruption, involving the greatest law firm of the nation, Taebak, which turns out to be one of the biggest scandals ever.
