After spending ten years deep in the mountains learning the language of animals, Lin Bei is driven down the mountain by her own mother and starts working as an assistant at a veterinary hospital. A husky swallows a screw, a ragdoll cat gets jealous, a vicious dog risks its life to protect its owner, and a Northeast China tiger goes wild for love. Strange cases keep coming through the door. The entire hospital thinks she's a fraud, while veterinarian Fang Mingyuan goes from doubting her to working alongside her. A video of her speaking tiger language goes viral, bringing reporters swarming and invitations pouring in. Lin Bei can understand the thoughts of animals, but discovers that the hardest illnesses to treat have never belonged to animals.
