The story focuses on Dingcheng Law Firm and its surrounding lawyer groups. Under the interaction of multiple lines such as an acquisition case, a murder case review, public interest litigation, and the change of power in the law firm, the six protagonists wander and struggle in the complex human gaps of the legal profession. The book uses humor and satirical language to reveal legal boundaries and ethical conflicts. Lawyers repeatedly run into obstacles in the face of ideals and interests, friendships and power schemes. They gradually awaken, grow, and reflect on themselves. In the end, they either redeem themselves, compromise, or stick to their original intentions. The three volumes go hand in hand, fully showing the successes and failures, and the light and shadow of human nature on the "legal battlefield".
