Yun Seok Hun is a partner lawyer and leader of the litigation team at Yullim Law Firm. He is a cool-headed risk-taker who pressures his opponents with creative logic. He is admired by his colleagues for his solid skills as a lawyer, but he is not easy to approach because of his cold attitude and complete lack of small talk. Kang Hyo Min is a rookie lawyer and works with Yun Seok Hun. She is socially awkward, but she is righteous and confident. She clashes with Yun Seok Hun over everything, but grows into a real lawyer.
A senior associate lawyer in his ninth year, An Ju Hyeong seems cold-blooded, but no one can deny his competence in the field. He became a lawyer simply because he found logic and cases interesting, but from the start of his career, he never grasped the idea that lawyers are supposed to protect the weak, uphold justice, and make a difference in the world. Although he's a veteran among associates and has even set a new salary record, he refuses to open his own practice, finding it too troublesome. But now, the once-peaceful walls of his workplace are beginning to crack. On the other hand, Kang Hui Ji, a junior associate at Johwa Law Firm, is a social butterfly who always ends up surrounded by people. She believes that “if you change one person's life, you have changed that person's entire world.” Whether she is lacking or overflowing, she is a confident and honest person. Alongside them are Bae Mun Jeong, Cho Chang Won, and Ha Sang Gi. These five lovable law firm attorneys struggle and grow through various cases, both inside and outside the courtroom, while building solid friendships by having meals together.
