After Tang Yuan unexpectedly gained the ability to understand the language of rats, cockroaches and other animals, he teamed up with a group of "animal informants" who spoke dialects and had different personalities to solve crimes. From the murder of his neighbor, to exposing the true identity of the serial "Rainy Night Murderer", to punishing the perpetrators of sexual harassment in the workplace, Tang Yuan relied on the clues provided by the animals and his own wisdom to help the police repeatedly solve strange cases. She has grown from an ordinary person running for bonuses to a criminal investigation consultant who shoulders justice and protects life, conveying the warm core of "all things have animism and justice will never be absent".
