The film tells the story of Gu Zhen, the leader of the serious crime team of a public security bureau, and his serious crime team members solving the case.

The case of police accidentally cracking an underground bank while chasing the suspect in robbery was reported in the news.While pursuing suspects who robbed gold shops, the Criminal Investigation Detachment of Huaizhou Public Security Bureau of Changzhou Province accidentally discovered an underground money shop in an abandoned old building. Nine suspects were arrested, two criminal gangs were destroyed, and funds involved were frozen.Fourteen million yuan, and a batch of tools for committing crimes were seized, including bank cards, vehicles, computers, U-shields, encoders, etc., with the amount involved reaching 75 million yuan.According to insiders, the police have set up a special task force based on the clues of illegally operating the money house to launch an investigation.

In a corner of the city, a girl was beaten and bruised and was held in an underground cage to call for help.Then a masked man splashed gasoline and lit the flames, the girl watched in horror as the fire spread and asked for help, while the masked man turned and left.Gu Zhen, the captain of the criminal investigation team in Changzhou City, performed outstandingly in this crackdown operation. As the captain who grew up from an ordinary policeman, he was widely reported by the news, and his photos became the target of hatred by criminals.

At a street stall, Qin Taian, a criminal investigation team member, was having a meal when he accidentally discovered that the man next to him was the wanted suspect.At this time, Gu Zhen entered the stall, exchanged glances with Qin Tai'an and began to carry out the arrest operation.Even if the suspect took out a big knife, it would be useless and was eventually subdued by Gu Zhen on the spot.Afterwards, Gu Zhen informed the stall owner that if there were any losses, he could go to the Criminal Investigation Detachment to find him.

The suspect was like a rat crossing the street during his five years of escape, but remained silent in the interrogation room.The words of Kong Rubai, a criminal psychologist at the Criminal Investigation Detachment, made him collapse and cry.Kong Rubai is about to be transferred here. He has a master's degree in psychology, is talented and has outstanding appearance.Gu Zhen successfully arrested the fugitive who had been on the run for five years, but Kong Rubai's arrival made him feel a little uncomfortable.It turned out that Kong Rubai was Kong Rusong's younger brother, and there was a deep bond between the two.

Gu Zhen received a call from Su Qian. While she was resting, she found that the suspect had participated in offline activities at an inappropriate time.Gu Zhen decided to arrest the suspect in person.When he came to the forensic doctor Su Qian, Su Qian advised him to verbally educate him and never use violence.However, Gu Zhen was very angry because the girl shouted slogans very hard among the star-chasing crowd. This is not the first time this happened.

When Gu Zhen returned to the bureau, he found that Kong Rubai had not returned. After learning that he had no place to live due to the renovation of the house, he invited him to live in his home for the time being.Soon, the Criminal Investigation Detachment received a new case: when the star Meng Zisu got up, he found a female corpse appeared beside his bed.The female corpse was dressed in cleaner clothes, but was dressed very delicately.The room card on the female corpse was from the cleaning lady. According to the cleaning lady, the dead girl was a fan of Meng Zisu. She gave her two thousand yuan to get her idol's personal belongings and got the room card and the cleaner's clothes.However, the surveillance near Meng Zisu's room was specifically told that it was not allowed to take pictures.But the team members found a hidden camera in Meng Zisu's room, and its terminal should be located in a room in the hotel.Gu Zhen assigned team members to investigate all rooms in the hotel.

Mencius was taken back to the bureau for interrogation and showed resistance.She confessed that she had been filming that day and went out for midnight snacks with the actors until about two or three in the morning.The agent Kelly sent Meng Zisu back to the room and said that she was also sleepy at the time and did not notice that there was anyone in the room at all.Mencius Su said she drank a glass of red wine in a daze. She thought it was poured by Kelly, but Kelly denied this statement.The entire floor was basically hotel staff, but the room opposite Meng Zisu was booked before the crew checked in, and a college student was checked in that day.

Xiaotang is a loyal fan of Meng Zisu. She plans to organize a flower wall support event tomorrow, and discuss with another fan on the phone with her on the phone how to give Meng Zisu the greatest support.Suddenly, a car deliberately approached her and scared her, and Xiaotang was so shocked that she sat on the ground.Immediately afterwards, a black bag was thrown from the car. Xiaotang complained and looked forward, but found a burnt hand exposed from the bag.Xiaotang was extremely frightened and immediately called Gu Zhen for help.

Due to excessive fright, Xiaotang was unable to attend class the next day, so Gu Zhen had to call her teacher repeatedly to apologize.Kong Rubai suggested that Gu Zhen provide psychological counseling for Xiaotang, because the suspect's behavior was extremely cruel and he burned the deceased and discarded it.The suspect has not been arrested yet, but the victim is the person they know - Yin Qing, who is the girlfriend of Feng Chao, the main culprit of the serial kidnapping murder case five years ago. She was sentenced to four years in prison for participating in the kidnapping. She suffered misfortune shortly after she was released from prison.Is this intentional revenge?But Feng Chao has been dead for five years. Who would take revenge on a dead person?Kong Rubai is interested in the case, but Gu Zhen has handed it over to other colleagues for handling, and their current focus is on investigating cases related to stars.

Gu Zhen and Kong Rubai came to the crew and asked the director about Meng Zisu's situation.The director complained about Menciusu, believing that he became arrogant and rude as soon as he became famous and was not friendly to people around him, and Menciusu could only vent his anger on his agent Kelly.The director has seen Kelly crying secretly in the corner many times.As for the deceased, the director did not know him and suggested that they go to Meng Zisu’s fans to find out the situation.Xiaotang happened to be among this group of fans, and after being discovered by Gu Zhen, she seemed a little guilty, but Gu Zhen and Kong Rubai were more focused on case investigation at this moment.Only Xiaotang and another girl knew the deceased. Xiaotang felt that the deceased looked familiar, like Lin Xiaojing. She was the leader of the ninth group of the fan club and was about to graduate from Huaizhou University.

The hotel booker was Wang Qian, a student from Huaizhou University. He went to the hotel to book a room that day, but his girlfriend failed to come, so he decided to go to the Internet cafe to play games overnight, so he was not in the hotel.Wang Qian cooperated with the investigation very well and also provided the name of the Internet cafe.Su Qian found the ingredients of obedient water in red wine, and the suspects are currently identified as Mencius Su and Kaili.Although the hidden camera in the room cannot be detected, there is a mystery hidden in the gift given by fans - a doll has a camera hidden in it.Through the camera, they found that Meng Zisu had an extraordinary relationship with his agent Kelly, and the person who installed the camera was Kelly.Kelly admitted to being in love with Menciusu, but Menciusu was unwilling to openly reconcile her and scolded her in front of outsiders, resulting in her being brutalized by fans over the years.Kelly wants to use the camera to sell it to paparazzi to reveal her relationship, but the camera is actually bad.

Meng Zisu actually knew that Kelly had installed a camera, so he broke it in advance.When Xiaotang and Anna left the hotel, Anna's friends came to pick her up, but Xiaotang did not travel with her because of something.The police gave Wang Qian the footage taken by the surveillance camera to identify. Wang Qian found that the person wearing the cleaning suit looked very much like his girlfriend Liu Sifan, and Liu Sifan was missing.Xiaotang once mentioned that Mencius's most popular drama was filmed on the rooftop, so Gu Zhen and Kong Rubai came to the rooftop of the school and found the suspect Liu Sifan.

The suspect Liu Sifan was standing on the rooftop, excited, holding Meng Zisu's pillow in his hand, and claimed to jump off the building after a disagreement.Gu Zhen and Kong Rubai were carefully persuading her to come down.However, Liu Sifan knew very well that Wang Qian had been taken away for questioning, and they must have known it.

Liu Sifan admitted that the development of the matter was far from what she expected.Since her debut, she has been crazy about him and is full of love for everything about him. Whenever she has the chance, she will try every means to get close to him.But she insisted that she was different from Lin Xiaojing and thought she was more intelligent than Lin Xiaojing.She once taught Lin Xiaojing various ways to approach Meng Zisu, but she did not expect that Lin Xiaojing would steal Meng Zisu's items and show off among the fans, which made Liu Sifan extremely dissatisfied.

This time, Mencius Su came to her city because of filming. Liu Sifan planned to act alone, but Lin Xiaojing took the initiative to contact her and asked to act together.The two of them made a surveillance doll together, but Lin Xiaojing only gave her own.Liu Sifan contacted the cleaner in advance, but Lin Xiaojing took the lead.

Lin Xiaojing sneaked into the room while no one was away, secretly photographed a large number of items and sent them to the fan group, and even threatened to take away the brooch and bracelet.Liu Sifan asked Lin Xiaojing to give her a brooch as compensation, but was rejected.So, Liu Sifan asked Wang Qian to book the room opposite the Mengzisu Hotel in advance, but told him that he could not go there.She asked Wang Qian's best friend to invite them to go to the Internet cafe for a night out and took the opportunity to disguise themselves as cleaners and enter the booked room.After Meng Zisu went out, she sneaked into her room and was immersed in the pleasure brought by this illegal act.

However, Lin Xiaojing broke in again, and Liu Sifan hid alertly, but found that Lin Xiaojing had stolen her creativity and drugged Meng Zisu's red wine.After the agent took Meng Zisu back to the room, Liu Sifan and Lin Xiaojing were very angry when they saw the agent helping Meng Zisu take off their clothes and untied them.

After the agent left, Meng Zisu drank the drugged red wine.Lin Xiaojing appeared behind the curtains and drank some red wine, preparing to take the opportunity to occupy Meng Zisu.She lay beside Meng Zisu and took a lot of photos.After witnessing all this, Liu Sifan will never allow Lin Xiaojing to defile his idol.So, she quietly put obedient water in the red wine, and Lin Xiaojing was confused after drinking it.Liu Sifan changed her back to the cleaner's clothes and asked her to stay in Meng Zisu's room for one night.She originally planned to make Mencius feel disgusted with Lin Xiaojing when she woke up, so that Lin Xiaojing would never be able to get close to Mencius.However, Lin Xiaojing's body overreacted to the anesthetic and vomited when she fainted, causing death from asphyxiation.

Liu Sifan felt deeply guilty and thought that he was both sorry to Lin Xiaojing and Meng Zisu.She felt that she had ruined Mencius' life and wished she could apologize for death.Gu Zhen and Kong Rubai told her that Mencius was taken away for investigation for tax evasion and had children in secret marriage.They think it is not worth dying for such a person.Liu Sifan heard that his legs were weak and he almost fell from the building. Fortunately, he was pulled by Gu Zhen and Kong Rubai in time.

At the same time, Meng Zisu's image collapsed, Xiaotang was in a low mood, and turned to fall in love with another idol.Gu Zhen felt helpless about her behavior of easily changing her idols.Anna was in a bad mood at the bar and fell asleep after being taken home by her brother.After waking up, she found a cup of hot milk on the table, and was surrounded by strange paintings.The sound of water from the bathing in the bathroom made her a little shy.

Xiaotang advised Gu Zhen to recover his sister, but Gu Zhen warned her not to meddle in other people's business and let her study hard.After hearing this, Xiaotang left angrily.Kong Rubai and Gu Zhen were discussing a robbery when they received a call saying that a murder occurred in the bar.

When Gu Zhen received a call, he learned that a murder occurred in the bar, he immediately rushed to the scene with Kong Rubai.In the bar, Su Qian was checking the body and found that the body had zombies. It was inferred that the death time was about three or four hours ago, that is, around three o'clock in the morning, and the suspect might have attacked from behind the deceased.The bar owner and waiter revealed that someone threatened to kill the dead last night.The person who said this was a female college student named Xiaotang. When she rushed into the bar, she claimed to kill Matteo, and Matteo responded that if he died tonight, it would be Xiaotang's doing it.Gu Zhen showed a shocked look after hearing this, and then Xiaotang was taken to the police station to cooperate with the investigation.

The deceased had only one English name, Mateo. The bar owner said he came every week and brought different female partners each time.The police recognized the deceased as a man named Liu Ang. He was an art teacher in a training class. He was good at human body painting. The female image he wrote showed a unique beauty and was hailed as a contemporary % of women's friends., well-known locally.When Xiaotang was under investigation, Gu Zhen was worried because Kong Rubai told him that Xiaotang was his ex-girlfriend's sister, and although he was not an immediate relative, he still needed to avoid it.Xiaotang admits that Liu Ang is one of her ex-boyfriends, and she did say in the bar that she wanted to kill him.At that time, Xiaotang and his friend met Liu Ang in a bar and were intimate with another woman. She slapped Liu Ang in the face in anger and smashed him with a bottle of wine, threatening to kill him, and was then taken away by her friend.After leaving the bar, Xiaotang walked with Anna, but left alone because she felt annoyed by Anna.

Xiaotang walked alone on a remote path and was pushed into the water by a masked man.She called for help in the water, but the old lady passing by did not give her help because of her unconsciousness.Fortunately, the water was not deep. Xiaotang took her own rescue and went to the public bathroom to organize it. Later, she went back to class after the school opened.The reason why she didn't go home was because she was homeless.Xiaotang originally thought that Liu Ang would just accuse her of hurting each other, but he was dead.

Gu Zhen suggested to Kong Rubai that Xiaotang’s personal identity information should be provided to see if it can be helpful for solving the case.At the same time, they learned that the deceased Liu Ang had advanced liver cancer, but he might not know it because the disease was not obvious.Kong Rubai speculated that there might be blood stains on the suspect's sleeves and has arranged personnel to retrieve surveillance videos.In addition, Liu Ang’s suit is very exquisite and is a high-end custom style. It looks quite luxurious for a lecturer. The whole suit is worth nearly 100,000 yuan.

Soon, another murder occurred not far from the bar, and a female body was found in the corner.After inspection, Su Qian judged that the death was also in the early morning, and there were signs of binding of the deceased's hands and feet.At the same time, Kong Rubai went to the suit store to investigate Liu Ang's situation. The owner said that although Liu Ang is not a regular customer here, he often comes to the store to buy clothes, and the female partners he brings each time are different, and it is these women who are for him.Pay the bill.

The women around Liu Ang are always willing to donate generously for him and never stingy in buying clothes.However, the store owner has a bad impression of Liu Ang. He believes that Liu Ang is the kind of person who depends on others, not on himself.Some of the customers in the store come independently, while others are taken with them.Liu Ang obviously belongs to the latter.Kong Rubai took out Xiaotang's photo to identify it for the boss. The boss confirmed that she had indeed come to the store. She was wearing a mask at the time and asked for a discount for living expenses.Gu Zhen called to inquire about the progress. Kong Rubai informed the DNA comparison results that Liu Ang was not Xiaotang. According to the surveillance, Xiaotang's whereabouts after leaving the bar have been clear, and the suspicion has been basically ruled out, but one thing needs to be verified with her.thing.

Gu Zhen went to the detention center to pick up Xiaotang, and on the way he blamed her severely, accusing her of chasing stars and being involved in the murder case too outrageous.However, Xiaotang and Liu Ang had only been dating for two weeks and had never bought clothes for him.Xiaotang cried and asked to go home. Although Gu Zhen was harsh at first, he finally felt soft-hearted and silently handed over a tissue.At the same time, Anna trembled beside her boyfriend, worried that Xiaotang would be mistaken for the murderer.Her boyfriend comforted her and said that her brother-in-law was a policeman and Xiaotang would be fine.When Anna asked her boyfriend how to know about this, her boyfriend smiled strangely, stroked her hair and said that it was Xiaotang who revealed it herself.

Bai Chang, a boy who found the female corpse, was taken back to the police station to assist in the investigation.He revealed that he organized a drink party last night and had a good impression of Xiaoxin, but before he could catch up with him, Xiaoxin left.Later, he was drunk and couldn't take a taxi. He fell drunk in the alley and found Xiao Xin's body when he woke up.Liu Ang’s suit is worth tens of thousands, Xiao Xin’s clothes are also expensive, and the shoes are worth thousands, and the signs on the clothes point to the store.After seeing the photos, the boss quickly checked the customer information and pointed out that Xiaoxin's fiancé Xu Dongyang is strong and has the ability to buy these clothes.At the beginning of last year, when Xu Dongyang's career was at its peak, he brought Xiaoxin to the store to shop.As for whether Xiaoxin loves Xu Dongyang deeply, it is difficult to judge, but Xu Dongyang's determination to marry Xiaoxin is obvious.

Anna breathed a sigh of relief after learning that Xiaotang had nothing to do, but sad that she would not be able to see her boyfriend Liu Ang again.Her emotions seemed not only because of Xiaotang, but also because of her boyfriend.Faced with Anna's silence and screaming escape, the police asked the women related to Liu Ang.The woman revealed that Liu Ang is a man who is a soft-hearted man. After breaking up with Liu Ang at a bar last night, she found a new love.She also mentioned that Liu Ang likes to shoot short videos of his girlfriend. A previous video was accidentally leaked, causing his girlfriend to commit suicide.In addition, Liu Ang and bar owners often have a disagreement over the competition for women.At this time, Kong Rubai sent a message saying that a short knife was found in the sewer of the bar.

The knife in the bar sewer was confirmed as the murder weapon that killed Liu Ang, and a fingerprint was also extracted from it. Because the sewer was abandoned, the fingerprint was retained.The fingerprints belong to the bar owner Lei Wei. Someone said before that Lei Wei has a tendency to violence, so Lei Wei is the most suspicious of killing Liu Ang, but Gu Zhen always feels something is wrong.There was a letter from Gu Zhen at the door. When I opened it, I found it was a provocative letter, which said, "I've been waiting for you to arrest me, I've been waiting for you to catch me for a long time."

The girl who committed suicide by Liu Ang was found out that her name was He Xiao, and she was dating Lei Wei when she committed suicide.Anna's boyfriend found out that Anna fainted from blood.Kong Rubai came to the place where Xu Dongyang lived, but a big boss like him lived in a very dilapidated building.Xu Dongyang's leg was injured. He said that he accidentally sprained his garbage downstairs two days ago. Surprisingly, Xu Dongyang's residence was quite clean.Xu Dongyang and Xiaoxin have broken up. Xiaoxin is looking for him because it is affordable. However, after his company went bankrupt, Xiaoxin called him to break up. Afterwards, Xu Dongyang asked Xiaoxin and said that he would make a comeback. I hope XiaoxinGive yourself some time, but there is no result.At three o'clock this morning, Xu Dongyang was having a video with his father and there was also a call record.When Xu Dongyang learned that Xiaoxin was dead, he changed his face and said with excitement that nothing happened to her had to do with him. Even if Xiaoxin died, she deserved it.

Such a strange reaction made Kong Rubai feel something was wrong. Xu Dongyang had obsessive-compulsive disorder, and there seemed to be something wrong in his room.Lei Wei was taken back to the interrogation room and firmly denied that he had killed Liu Ang and said nothing.Speaking of He Xiao, Lei Wei also said that she had died a year ago, and they had broken up before her death.After Lei Wei and He Xiao were together, they found out that she and Liu Ang were in the ex-boyfriend and girlfriend. Later, he also received a short video sent by Liu Ang, so Lei Wei couldn't stand breaking up with He Xiao.Su Qian found that the fingerprints on the knife also had some adhesive, so it is very likely that Lei Wei's fingerprints were glued to the tape.Lei Wei was already a little impatient and said again that He Xiao was not worthy of killing her.

The suspect's method of committing the crime was very detailed and it should have been planned in advance. The underworld coins stuffed into Xiao Xin's mouth did not leave any fingerprints.After Anna was hospitalized, Xiaotang was very worried. She took the flowers to visit Anna. Anna said she wanted to talk to her alone, but after the two of them, Xiaotang left the hospital angrily.Anna failed to commit suicide, and she confessed to Xiaotang that she gave her boyfriend Liu Ang to her, but Xiaotang was not willing to accept her statement.

The DNA comparison result came out, and it was not Lei Wei who killed people.Gu Zhen found that there were five waiters at work that day, but there was one more surveillance video. Gu Zhen believed that the suspect was also likely to have something to do with He Xiao.The clue pointed to the clothing store owner. He planned all this with his own hands to avenge He Xiao.
