In 2001, in a small northern town, Wang Hong, an Internet cafe administrator, rescued a woman who gave birth in the Internet cafe by chance. As a result, he was involved in the Meihua Gang's human trafficking, murder and other crimes. Later, Wang Hong cooperated with the police and secretly investigated the Plum Blossom Gang. After capturing members of the local criminal organization, he continued to fight against evil criminal gangs such as mine thieves.
