Nanya used to be outstandingly beautiful and versatile, and she once became the focus of attention among her classmates. But since her mother passed away, the so-called "stepmother" Hu Xiu appeared with her son Hu Lifan, and Nanya's life gradually turned dark. Hu Lifan was only slightly older than Nanya. Whenever he looked at his half-sister, his eyes were filled with lustful evil that could not be ignored.
Nanya originally made an appointment with Lin Fanglu and others to watch the meteor shower, but she was harassed by drunken gangsters along the way. Although Hu Lifan appeared in time and took Nanya away, he was already ready to implement his long-planned evil idea. In the end, Nanya failed to resist and suffered a shameless violation in the woods. Afterwards, Hu Lifan walked away, leaving Nanya trudging toward home like a zombie.
At this moment, Nanya's father was humming a tune, Hu Xiu was in a good mood, and Hu Lifan was eating noodles nearby. The family of three seemed warm and harmonious. However, Nanya went straight forward and smashed the noodle bowl, turned around and rushed into the kitchen to get a knife. Nan's father was upset when he saw this and raised the shovel angrily, but Hu Lifan snatched it away and punched him. Kick.
In order to prevent Nanya from calling the police, Hu Xiu and her son locked her in the woodshed. And Nan's father knew that his daughter had been defiled and he had been beaten, but he still knelt in front of Hu Xiu and begged for forgiveness. That night, Hu Xiu took advantage of Nanya's unconsciousness to clean up her blood and residue, completely erasing the evidence of her son's crime. Nan's father could only stand at the door and cry sadly.
Nanya didn't come to school the next day, which aroused everyone's confusion. Lin Fanglu asked Nan's father about the situation, but Nan's father smelled of alcohol and ignored him. Finally, he lied that Nanya was sick and asked for leave. At the same time, Nanya was still locked in the room. Nan's father brought food and persuaded his daughter not to call the police, because now is a crackdown, and Hu Lifan may face the death penalty if he is caught, and the family will be torn apart.
Nan's father hopes that his daughter will marry Hu Lifan after graduation, thinking that the two have a substantial relationship. If she does not marry Hu Lifan, I am afraid no one will marry a woman who has lost her virginity. Listening to her father's words, Nanya's heart sank to the bottom. She finally understood why her mother was disappointed in her father, and she also hated being born into such a family.
After Lin Fanglu learned what happened to Nanya, he was shocked and angry. Even Lao Chen found it incredible that there were so many vicious people in a small Qingshui Town. Because of this, Lin Fanglu got drunk alone by the bridge, listening to the singing from his alma mater, and recalling Nanya's past of dropping out of school. He hated himself for being weak and incompetent, for failing to protect Nanya, and for not having the courage to take her away from this place of right and wrong, because if he made the wrong choice, it might take years or even decades to pay the bills, and he didn't dare to gamble.
Early the next morning, Lin Fanglu found the restaurant where Xu Yi and Liu Changshui met through the photos taken by Xu Jian. However, the restaurant has been closed. The administrator revealed that the restaurant was formerly a car repair shop, so Lin Fanglu got an important piece of information: Wu Shangui, the car repairman, did not go out, but married a wife and had children in Furong Town next door, and opened a mahjong parlor.
Later, Lin Fanglu and Lao Chen went to the mahjong parlor to investigate in person. They learned through Wu Shangui that Xu Yi had driven here in the middle of the night five years ago and asked Wu Shangui to check because the car broke down. During this period, Xu Yi behaved a bit strangely and even prevented Wu Shangui from opening the trunk.
According to Wu Shangui's recollection, there was a woman in the car at the time. Lin Fanglu and Lao Chen speculated that if this person was Nanya, it was most likely that she and Xu Yi teamed up to kill Hu Lifan and dump her body in the suburbs. In order to deceive others, the two needed a ticket inspector to provide an alibi, which was consistent with what Xu Jian said of "concealing an affair." Lin Fang drove along the road to the suburbs and found a large lake in front of him, and his first instinct was that Hu Lifan's body was most likely dumped here.
