A Xin (20 years old) is a top student at a law university and a provincial science champion with strong reasoning ability. On this day, one of his friends, A Zhuo (18 years old), a prospective freshman, encountered a porcelain case. In this case, they also met Aji (45 years old), a veteran policeman with many years of experience in investigating crimes. After solving the case, they formed a detective team. After that, they also met more friends, including A Cheng (28 years old), an English teacher in a cram school with a dream of being a detective, and A Hou (26 years old), a private doctor of a wealthy family. The five are the five heads of this detective group. They often encounter various cases in their lives and explore the truth, but A Xin always thinks in the center of his mind: "I really don't want to solve the case!"
