Scorching Sun

In 1999, a series of home invasions, robberies and murders occurred in City C (Chongqing). Based on the situation at the scene, the police speculated that the murderers were two Bangbangs. The police repeatedly searched the Bangbang group, but could not find the murderer. Interpol captain Xu Wei speculated that the murderers were two educated Bangbangs, so he searched among this group. At the same time, 10-year-old Xiao Heling went to the city to visit her father, who was Bangbang, and met Chen Jianghui's family. On her 10th birthday, her father was involved in a robbery and murder case. When the police thought that Xiao's father was the murderer, Xiao's father was killed along with four other Bangbangs. There is a strange pool in the rental house, and there is a row of unknown numbers on the wall. The case has not been solved for a long time. Xiao Heling, who became an orphan, grew up to become a criminal police officer and an excellent criminal forensics expert. In 2022, the Ministry of Public Security launched "Operation Cloud Sword" to start tackling difficult cases. The real culprit behind this massacre that spanned 23 years was finally arrested.
