In 2000, a pupil on holiday lived in the home of his teacher Xia. When he went out to buy fish in summer, he was followed by a man in black and was killed in the house.
On the other hand, those who just joined the major crimes unit are eager to solve major cases. Under the introduction of Daming Zun Zhu Chen, he learned about the biggest case in Haizhou in recent years-Haizhou serial murder.
Later, it happened that the Gao Peng brothers went to the police station. On the first day of work, Leng received a mysterious call, and Leng and Interpol Li Lan rushed to the scene. Because the informant didn't say the specific house number, he had to look for it separately.
Leng found Xia's home all the way, and happened to bump into the murderer. Due to excessive tension, Leng was stunned by the murderer instead of shooting with a flowerpot. The murderer was stopped by Li Lan on the way to escape. In order to get away, he brutally killed Li Lan.
Daming Chen and Gao Peng rushed to the scene. He speculated that the alarm call was made by the murderer, and the same fingerprints were found on the public telephone and the posted notice, which confirmed that the murderer had burns on his right hand.
2. The second episode
17 later, Natsume came to the police station to report the case. Gao Peng, the receptionist, was very surprised to learn the identity of Xia Yu. Natsume insisted on going to homicide, which deepened Gao Peng's suspicion. I wanted to discuss it with Leng, but Leng was in a hurry to go to the police, so I left with him and ignored the instructions.
At the scene of Ma Yu's case in Forest Park, the technical team found a 39-yard footprint beside the deceased, which was suspected to be the suspect's, but the identity of the suspect could not be determined. After investigation, it is speculated that the deceased must have a carry-on bag, and the loss of the carry-on bag is a major doubt at present.
Moreover, according to Xia's analysis, it was a vendetta, and the suspect wanted the deceased to apologize for something. The analysis won the cold favor, and he invited him back to the police station together. On the way, he asked the name of Natsume. After learning about it again, he was surprised and went back to the police. Leng was worried about coming back with hatred to investigate the sinking case, so he stayed with him.
3. The third episode
At the case analysis meeting of Ma Yu's case, Natsume discovered the problem of footprints at the scene and judged that the 39-yard shoe prints at the scene came from two people. Through the arrangement of footprints at the scene, he inferred a place where the police went to dig, and indeed dug up the bodies of many animals, thus inferring that Ma Yu was a person who abused animals, and the suspect killed Ma Yu to make him atone for these animals.
Therefore, the suspect is likely to have a pet, and the pet was also killed by Ma Yu. Leng Xiaobing came to Ma Yu's home again and found many dog chains and labels from his drawer. According to his wife, Ma Yu not only abused animals, but also recorded videos and returned them to the police. Leng asked to go to the archives to investigate the cases of lost animals in the past five years.
Natsume came to the archives to check the case files, but was interrupted by the police officer who came to get the files. This just know haizhou case to restart. On the other hand, Leng also saw that the files of Haizhou were transported away in batches. The police officer explained that Haizhou's case had been reopened, but Gao Peng told him that the major crimes unit was not allowed to participate.
Natsume found a car burning case caused by a pet dispute from the file. The suspect's name is Xiao Huajun, but strangely, when the car burning incident happened, his psychologist Shen Yu actually provided an alibi, so Lenghe came to Xiao Huajun's home.
4. The fourth episode
Xiao Huajun fell to his death and rushed to the scene to call Xiao Liuhe. Natsume wakes up from the meat wholesale market and returns to Shen Yu's house. It happened that Shen Yu got on the elevator. Shen Yu said that he went downstairs to buy breakfast and told Natsume that he had blood on him. Don't be found by the police.
Natsume came to the murder scene, but because it was concrete, it was impossible to judge whether there was a second person at the scene. Natsume knew that during the period when he fainted, Shen Yu was likely to commit a crime, so he wanted to find Leng to confess. He passed by Gao Peng's office and went in to admit his mistake to Gao Peng.
Gao Peng wanted to punish Natsume, but was protected by the cold. The next day, I respected Leng's opinion and only wrote a check.
After forensic analysis, Xiao Huajun's fall was very strange. It was neither a natural fall nor a push, but he ran and jumped down the stairs. Combined with the investigation of the technical team, we found the weapon used by Xiao Huajun and confirmed that Xiao Huajun was the murderer of Ma Yu.
However, due to the death of Xiao Huajun, Gao Peng applied to the Municipal Bureau to suspend the investigation. But cold is very reluctant to find Shen Yu.

However, Leng found that the scald on He Weiguang's right hand was consistent with the murderer of Haizhou case. Under the cold questioning, He Weiguang didn't give out the clues.
Cold and at the same time, why does Weiguang feel uneasy? They came to the slaughterhouse where He Weiguang worked, but after careful observation, it was determined that He Weiguang was not the murderer of Haizhou case.
