Tang Yuan, an ordinary poor social animal, unexpectedly has the special ability to understand the language of mice, cockroaches, flies and other small animals. At first, he only offered rewards for solving crimes to improve his poor life, and became a special consultant to the police. She relied on the Rat Pack and the Cockroach Squad to serve as informants, and successively solved the serial murder cases of women living alone. She also used small animals to collect evidence, revealing the truth that her boss Ma Huan had sexually assaulted his subordinates for a long time and was poisoned to death by the victim Feng Lingling, and helped many female victims to gain understanding and obtain lighter sentences. The unsolved case of dismemberment on a rainy night that had been backlogged for six years in Beishan City was difficult to solve. Tang Yuan led the animal detective team to provide support and sneaked into wealthy families to collect key evidence.
