Veterinarian Lin Fan awakens the animal voice translation system and starts a live broadcast to answer questions and solve the case. He used a ragdoll cat to expose his girlfriend's cheating and cat abuse, used a pastoral cat to uncover her boyfriend who was secretly filming him, helped a detective dog to take out a drug dealer's den, and relied on a teddy dog to solve a poisoning and murder case. He became famous as the "Animal Detective" and attracted the love of policewoman Su Qing and landlord Liu Man. After the system was upgraded, the miracle drug he developed was coveted by the pharmaceutical giant Wang Quan. The other party pirated the medicine and sent killers to retaliate. In the end, Lin Fan used ants and other animals to find evidence of the underground factory, exposed his crimes in the live broadcast room, and successfully brought him to justice. He also formed a detective supernumerary team with Su Qing and Liu Man to continue to use his special abilities to protect justice.
