A series of extortion cases took place in Shuangqing City. According to the information gathered by the police, the suspect used phone cards that required no real-name registration to photograph sex workers and extort them. The person who collected the money wore a delivery uniform and a motorcycle helmet. Despite several police attempts to stake out the suspect in advance, they still managed to get away. Just as the police were closing in on the truth, the suspect was unexpectedly caught after someone reported them. As the evidence piled up, however, the investigators handling the case realized that the person they had arrested hadn't acted alone. To find the real culprit, one investigator tried every possible approach, unaware that even greater danger was lurking close by. A zero-sum game with no winners or losers, brought into reality. People are constantly locked in tense contests with one another, and everyone faces one choice after another. The world isn't so simple, nor is it black and white. There are no purely good or bad people. Everyone has a vulnerable side and a reckless side. Life is just one unexpected turn after another, following what seemed inevitable. Cause and effect come full circle: sow good seeds and reap good fruit. Sadly, things don't always go as planned, and sometimes every effort is in vain.
