Bingwu Year of the Horse, Yangzhou. A corpse carrying thousands of kilograms of fake salt shocked the rainy night at the water transport terminal. The head catcher Zhao Tieying was ordered to conduct a secret investigation, from the back alleys of the market to the deep courtyard of Yanzheng Yamen, gradually tearing apart a huge web woven by forgery, corruption and murder.
