At 22:17, Zhou Xu, a researcher at the people's livelihood hotline, received a task that only he could see: to completely cut off power to a residential building before 23:00. If the mission fails, his body will be gradually taken over by the system. Faced with the mysterious system that constantly forced him to do evil, Zhou Xu neither obeyed nor concealed it. Instead, he handed over the task to the investigation team and regarded it as dangerous information. The power outage was to save people, and the evidence was destroyed to lead to the real culprit. As investigator Lin Jianwei joins the investigation, those seemingly absurd villain missions gradually point to a black network covering the entire city. But they soon discovered that Zhou Xu was not the only person who received the mission.
