In the legal arena of modern cities, Zhou Qiming leads a group of lawyers across borders to detect major cases and resolve social conflicts. They were tit-for-tat and full of jokes during the case. Lawyers and prosecutors, police and forensic doctors, judges and newcomers grow up in a complementary manner - idealistic and down-to-earth, not only exposing the conflict between law and society, but also using humor to heal the bitterness of reality. Each volume is based on a case, analyzes human nature, and is both independent and connected to the main line. The group of people struggled between career and family, emotion and justice, and finally defended justice in their own way, and moved toward personal and collective maturity.
