Hua Muyao was dating her boyfriend Wen Jing, and Wen Jing took her to a small building by the sea. As soon as she entered the door, Wen Jing told Hua Muyao that she was going to kidnap her. Wen Jing called Hua Muyao's father, Principal Hua, to ask for a ransom of three million yuan. Hua Muyao's fiance, Chen Yanfei, wanted to call the police, but Principal Hua refused to call the police for fear of her daughter's life.
Hua Muyao, who was tied to the stool, cried sadly and scared. Wen Jing carefully wiped away her tears. He said that he didn't want to hurt Hua Muyao at all, but he had to kidnap her. When Wen Jing left the small building, he sent a message to a person named Brother Duan, and he planned to leave the rest to Brother Duan. Hua Muyao pulled out the iron stick that fixed the stool in constant struggle. After the stool fell apart, Hua Muyao broke free and finally smashed the window and escaped successfully.
Hua Muyao went to the police station to report the case. Li Han searched the population information system according to Wen Jing's name, but found nothing. It seemed that Wen Jing was a fake name used by the kidnappers. Shen Yi was in a daze at a portrait of a woman who could not see her face clearly, and then received a call from Li Han. Shen Yi drew a portrait of Wen Jing based on Hua Muyao's description.
Du Cheng led the police to investigate the small building by the sea. He found that the kidnappers might not know that Hua Muyao had fled, so he decided to set up control around the small building. When the dawn was about to break, a man riding a battery car came to the small building by the sea. The city took him back to the police station for questioning. The man's name was Chen Mingfeng. He said that a man named Duan asked him to come to the small building by the sea to deliver meals, and the two met at a bar. Jiang Feng led people to search Chen Mingfeng's home and found uncommon konjac and a large number of pig trotters.
Principal Hua and Chen Yanfei, who were notified, came to the police station. Chen Yanfei was furious because Hua Muyao had a boyfriend, and Principal Hua, who lost face, slapped Hua Muyao. The emotional Hua Muyao accused Principal Hua of just wanting a son-in-law who would make him look good, and didn't care who he liked at all. In private, Shen Yi advised Principal Hua to respect Hua Muyao's choice.
Du Cheng went to the bar to learn about the situation, but the bar owner was unwilling to cooperate. It was not until Du Cheng proposed to search the bar that the bar owner remembered the hot-tempered and light-drinking brother Duan after being reminded by Du Cheng. Du Cheng showed the photo of Chen Mingfeng to the bar owner. The bar owner said that Chen Mingfeng came to the bar to drink the cheapest wine and was low-key.
The kidnapper sent a message to Principal Hua to ask for a ransom. Du Cheng persuaded Principal Hua to cooperate with the police. In the end, under the comprehensive monitoring of the police, Principal Hua took the box containing the money and got on the subway line designated by the kidnappers. The technicians of the police station searched for the mobile phone signals of Hua Muyao and Duan Ge. Du Cheng led the police officers to ride the subway with Principal Hua, while Shen Yi drew Duan Ge’s portrait at the police station according to Chen Mingfeng’s description.
The subway station was approaching the end, but the kidnapper never showed up. Du Cheng urged Shen Yi to complete the portrait as soon as possible. Principal Hua received a text message from the kidnappers on his cell phone. Principal Hua had to leave the box and get off the subway. Shen Yi completed the portrait between revisions. The technicians found Hua Muyao and Duan on the edge of the end wall outside the small building by the sea. Brother's cell phone. According to the portrait, Du Cheng did not find Brother Duan at the subway station. He understood that he was tricked by the kidnappers, and the text messages sent by Brother Duan's mobile phone were likely to be set in advance.
Li Han compared the portraits of Brother Duan and Wen Jing with the database. Although he found nothing, Du Cheng still believed that the portraits given by Shen Yi were accurate. Du Cheng arranged for people to visit where the kidnappers might appear, and he took Jiang Feng to find a woman who kept a high-frequency call with Brother Duan, but neither side got any clues.
Shen Yi and Li Han asked Hua Muyao to make a supplementary transcript. Chen Yanfei hoped that the two would not disturb Hua Muyao again, and Hua Muyao wanted to talk to Shen Yi alone. Hua Muyao and Wen Jing first met at a piano audition, and then Wen Jing began to pursue Hua Muyao in the form of letters. In the end, the two fell in love. What makes Hua Muyao strange is that Wen Jing often chooses to date her at night. Shen Yi checked Wen Jing's letter to Hua Muyao and took it back to the police station.
After repeated investigations, all the clues were interrupted. Du Cheng thought that there must be a problem in some part of their investigation, and Shen Yi also felt that the kidnappers could not be completely disappeared after committing the crime.
