In modern Yinling Town, a century-old mystery is buried beneath the bustling city. A sudden wave of ghosts and monsters plunges courier Zhang Xiaobao and Taoist priest Li Banxian into a supernatural whirlpool. Together with the witty teacher Liu Yuanyuan, the strong-as-an-ox butcher Wang Tieniu, the girl who can see ghosts Lin Xixi, and the know-it-all Mr. Hu, they form a strange ghost-killing team, and they encounter evil ghosts, monsters, ancient houses, mysterious disappearances, and unsolved curses from a hundred years ago...

After going through conflicts and funny adventures, a different kind of bond is formed between people and ghosts, and the ultimate secret that has been hidden for hundreds of years in Yinling Town is finally revealed, ushering in a new era of peaceful coexistence between ghosts and humans.
