Eight years ago, the uncovering of a large-scale drug trafficking case revealed a huge criminal group rooted in southern China and with influence across the country. Their poisonous horns extend to the Chinese border and even Southeast Asia. After four months of searching for clues, the criminal police accidentally captured Chen Shifeng, the top executive of the criminal group. However, the investigation work subsequently encountered strong resistance. Chen Shifeng's silence and the disappearance of the criminal group left the police helpless and the case was shelved.
Eight years later, the criminal gang showed up again. This time, it was imperative to dismantle it.
