He Yuan, a graduate in veterinary medicine for livestock, can only work as a temporary worker shoveling horse manure at a private horse farm after facing setbacks in his job search. After a high fever, he unexpectedly awakens a special ability: the capability to hear the inner thoughts of animals. The complaining racehorse in the stable and the grumbling guard dog are all sharp-tongued. At a competition, the champion racehorse T-Xue suddenly falls seriously ill, and a group of veterinarians decides to perform euthanasia. Relying on his ability to understand animals' inner voices, He Yuan discovers that the horse only has gravel stuck in its horseshoe, saving a racehorse worth tens of millions and making a name for himself from then on.
