In the twelfth lunar month of Beijing, in search of the missing pony "Ben Ben", Beibei, an alley girl, accidentally broke into the mysterious Liulifang and learned that she was a "horse whisperer" who could understand horses.
The Golden Horse God's glass heart was stolen by Black Nightmare, causing the horses in the city to get lost.
Beibei and her friend Qiqi followed the clues to the Forbidden City. Under the guidance of the revolving lantern in the Clock Museum, they retrieved Liulixin and helped the Golden Horse God defeat the Black Nightmare. In the end, "Ben Ben" returned safely, and Beibei also shouldered the new mission of guarding the city's horses.
Mission: Innocence protects tradition, courage lights up hope.
