Fifteenth Minute

In Nanhuai City, Jiangling Province, the municipal party committee and government are implementing a "15-minute emergency response circle". Just before the promotional event started, police officer Xu Tinglan received a strange alarm call. The man on the phone had a calm voice and only said one sentence: "In fifteen minutes, a woman will die under the West Bridge." When police arrived, the woman was still alive. There was no killer, no weapons, and no apparent danger. But when fifteen minutes were up, she still fell down in front of all the police. From that day on, similar calls came to the police center one after another. Each time, the reporter was able to accurately tell the place, time and state of death. Chen Du, deputy captain of the Criminal Investigation Detachment of the Municipal Public Security Bureau, led his team to the scene again and again, but watched helplessly as deaths happened on time. He originally thought this was a provocation from the murderer to the police. Until he discovered that reporting a crime was not a warning. Reporting the crime itself is part of the killing. What the murderer really used was not a knife or a gun, but the police's dispatch procedures, first aid response, and people's most instinctive choices in critical moments. As the investigation deepened, Chen Du and Xu Tinglan discovered that behind these cases was an old case from Nanhuai City fifteen years ago. That was an alarm call that was not handled properly. Now, someone is trying to force the city to hear it again with a series of deaths.
