In the 1990s, the wave of reform and opening up swept across the country, and remote towns and villages could not escape the torrent of the times. Han Xu's father runs a private flour mill in a township, but struggles to survive amid irregular systems and policies. Enterprises cannot escape the fate of bankruptcy in the end. Han Xu witnessed his father's submissive attitude in front of others, experienced oppression from evil forces, was robbed during delivery, and was ridiculed. The company went bankrupt, and his father died unexpectedly while away from home, all of which deeply hurt Han Xu's heart.
After the college entrance examination, Han Xu resolutely applied for the police academy, determined to join the police, answer his doubts, and change the face of society. After graduating from the police academy, he returned to his hometown without hesitation and started as a grassroots police officer. In a remote town, he felt confused for a time until he met a workaholic master and started to get involved in case investigation. From theft cases to corpse dismemberment cases, from drug crimes to underground transactions, Han Xu gradually discovered that there was a bigger sinister hidden behind these cases, and the worms at the top of the city were the root of it all.
