Black and White Code

The play tells the story of five years ago, when the police severely damaged the "Northwest Wolf" criminal group, but the leader Gu Mulan, the backbone Lao Qiang and the undercover police dispatched Lin Ke and others were all missing, and their lives and deaths were unpredictable. Five years later, the "Northwest Wolf" group reappeared. In order to find his mother Lin Ke (played by Liu Weiwei), police officer Chu Yihan (played by Wang Ziqi) took the initiative to become an undercover agent and infiltrated the criminal group. With the support of Cheng Fan, the former deputy criminal investigation detachment leader and the main executor of the Northwest Wolf case that year, he further penetrated into the core of the criminal group. In the process, Chu Yihan and Gu Linna (played by Su Xiaotong) met and developed a good relationship with each other. The two experienced a series of conspiracies together, and finally cleared up the fog amidst the dangers.
