Li Ming, a special member of the Central Committee, was appointed to conduct an unannounced visit to Chang'an. He kept a low profile and went deep into the corners of the city. In Chang'an, he witnessed gangsters bullying an old man selling fruit and forcibly collecting protection fees. He learned that factory owners colluded with the underworld to delay workers' wages and threaten workers who defended their rights, as well as prostitution, drug trafficking and other illegal activities behind entertainment venues. Li Baiming pretends to be a migrant worker and goes deep into gang-related enterprises during the day, and follows suspicious persons to collect clues at night. When he was preparing to take key evidence back to the central government, he was targeted by the evil forces and attacked by a killer. However, he successfully subdued the killer in a fierce fight and finally returned home with the evidence. Chang'an is about to usher in the anti-crime storm and the dawn of justice.
