The body of a beautiful girl was found in a luxury villa, and the criminal police captain Guo Zijian led the team to the scene. After verification: the deceased, He Xiaoyu, was newly married; the fatal weapon was a knife in the house, no property was lost, and there was no sign of theft or fighting. Everyone saw that her husband Wu Youan had a fierce conflict with Xiaoyu not long ago. However, Wu Youan could not prove that he was not at the scene when the crime occurred, and became an important suspect. The report on Xiaoyu's body revealed shocking facts. The deceased was changed from a man to a woman after a sex change operation, and had been sexually assaulted before his death... Before the wave was over, the criminal police team received another report: a female body was found by a fish pond in the suburbs of the city. After examination, the deceased had a large amount of strong sleeping pills in her stomach and semen stains on her clothes. The criminal police team found a suicide note in the deceased's office, claiming that she was raped many times by her immediate superior, Director Wang, and then she took the road of suicide in anger. After DNA comparison, it was found that the semen stain was left by Director Wang. It seemed that the truth was revealed, but the overly simple case caused doubts for the criminal police captain Guo Zijian... At the same time, a rape case occurred on Bar Street. After Hu Jiajia left the bar, she was raped in the alley. The forensic doctor extracted the semen left by the suspect. The criminal police team wanted to use this as a breakthrough to lock the suspect, but found that it was impossible to convict the criminal based on DNA... At this time, the granddaughter of the traffic director disappeared... Several vicious rape and murder cases and missing people in succession made people in City A panic. The Public Security Bureau of City A issued a death order to solve the case within a time limit. The criminal police captain Guo Zijian, police officers Meng Fanjun, He Chuan, Wu Tong and others formed a special task force code-named "Snake Inducing Operation". These cases seem simple but are full of questions. Is it trafficking or kidnapping, organized crime or unrelated, is the murder a rape followed by silence? Or is it to hide more serious crimes... The major case arrest task force uses rich knowledge, careful reasoning, scientific methods, and hard investigation to unravel the case and find the suspects, making the case clear to the world. The second part of "Crime Scene" reflects the criminal police team of a metropolis in northern China. Faced with "homicide", "kidnapping", "stealing secrets", "adultery", "drug trafficking", "cybercrime", "money-stealing" and other crimes with distinct characteristics of the times, the detectives use rich knowledge, sharp eyes, careful reasoning, scientific methods and hard investigation to find the suspects accurately and timely again and again, making the case clear to the world, punishing evil and promoting good, and maintaining social order and the dignity of the law. __The 36-episode TV series "Crime Scene 2" is a sublimation of the famous legal TV puzzle column "Weekend Detective". Many of the cases involved in the play are classic materials in the column. At the same time, some real cases have been carefully selected from a large number of criminal cases that have occurred across the country in recent years. On this basis, more than a dozen outstanding film and television screenwriters have been organized to carefully plan and revise the manuscript several times. On the basis of the vivid and attractive plot, "Crime Scene" is different from general suspense dramas in that it focuses on the way of technical investigation and shows a large number of means of solving cases, which makes the audience feast their eyes. The process of solving cases involves a variety of forensic disciplines, including forensic medicine, toxicology, DNA identification, traceology, fingerprints, trace evidence, scene analysis, ballistics, forensic entomology, crime scene reconstruction, document inspection, voiceprint identification, skull restoration, criminal psychology testing, etc. The play shows the new ideas and new methods of public security officers to solve cases with high technology, and fully demonstrates the new face of public security personnel in the new era, which is younger, more knowledgeable and professional. Let the audience feel the pleasure of being in a criminal investigation laboratory and appreciate the scientific argumentation process of the police elites who are keen on the slightest detail.
