A city that always wakes up at midnight, a "nightwalker" who takes commissions in the shadows, and a "secret keeper" who guards all the secrets of the city.

When a supposedly dead body knocks on Gu Yexing's door again, the two are forced to join forces to track down the truth, only to find that they are stepping step by step into a huge scam that has been woven for thirty years.
