Lu Baoliang (Huang Ming) had a happy childhood. His proud father Lu Weiguo is the captain of the Criminal Investigation Brigade of Jianning Public Security Bureau. He also has a gentle and kind mother and a beautiful and lovely sister, Bao Zhen (Claudia). At the age of ten, Bao Liang imitated his father's appearance, kowtowed to his best classmates Liu Cunliang (decorated by Qu Gaoguan) and David li Chen, and named himself "Jianning Three Brothers". My father's brother's family has always had a good relationship with Lujia. All the adopted sons fired three shots, and every time he fought, his father came forward to save him. At the age of eleven, Bao Liang's father had an accident on his way out after three shots. From then on, he became a cripple. He was transferred from the Criminal Investigation Brigade to the local public security school as the vice principal. The father who has been silent for a long time has become more silent and has higher and more urgent expectations for his son. I hope he can inherit his father's wishes and be an excellent policeman. Bao Liang discovers unexpectedly that her sister is secretly in love with Quan Jia's son Hu Quan (Yuan Wenkang). After a close talk with my uncle, my father resigned from the police academy and joined my uncle's company. After my sister's relationship with Hu Quan was known by my father, my father strongly opposed it. The lovers finally chose to escape. Before leaving, mother gave Bao the white gold earrings and asked him to give them to his sister. On her 55th birthday, my sister and her newborn son returned to Jianning. On that day, power and his subordinates were arrested by the Public Security Bureau on suspicion of illegal fund-raising and underworld crimes. Power was sentenced to death and disappeared after Hu Quan and Bao Zheng were acquitted. My father made great contributions to the power case and moved his family to the provincial capital. My mother was getting haggard because of her sister's departure. A few years later, she died of depression. When she died, her mother gave Bao Liang another white gold earring and told him that he must find his sister. Since then, looking for my sister has become a knot that Bao Liang can't open. Father got married again, so Baoliang had a stepmother, Aunt Yang, and a younger sister, Dudu (Wang Shasha), who he didn't like. Later, his brothers Liu Cunliang and Chen Li also came to the provincial capital. Bao Liang also meets Liu Cunliang's girlfriend Feifei (Li Qian), who has an important influence on his life. Bao Liang was finally admitted to the police school in the provincial capital, where he met Xia Xuan (Zhang Li), a senior he will never forget.

Those who work in the night club of Fireworks Capital heard the word "right tiger" from a boss Ma. Bao Liang regards this as the only clue to find his sister. He looked for boss Ma many times, but the other party refused to give him any information, and even sent his men to beat him. Just when Bao Liang was disheartened, Ma Boss's mistress found him and promised to help him find his sister, but only if Bao Liang wanted to "play" with her. In order to find his sister, Bao Liang was forced to accompany Xiao Guai to some ecstasy-eating parties. At the last ecstasy party, the police who broke into the house suddenly arrested them. Bao Liang was expelled from school. Once, after taking ecstasy, mobster committed suicide by jumping off a building. Before she died, she asked a friend to give Bao Liang a business card. With this business card, Bao Liang found an old yard that Ma had rented before, but he accidentally met all three cannons there. Bao Liang took home the right to see his father three times, but he didn't expect to bring a tragic disaster. The right of revenge shot and killed Aunt Yang and Dudu three times, and Bao Liang fled hastily and reported the case in a hurry. In grief, my father drove Bao Liang out of the house. Baoliang has no choice but to invest in two brothers and live with Feifei, who has always loved him. Baoliang got a job in a cleaning company, and got to know Zhang Nan (Wang Yuanke), a beautiful and elegant white-collar girl. There is love between them, but due to the disparity in social status and age, they are opposed by Zhang Nan's parents, and there is a fierce dispute between Baoliang and Feifei. Just when his relationship with Nan improved slightly, Feifei's mother needed a large sum of money to treat her illness. In order not to let Feifei go to be Miss Taiwan Province, Baoliang had to bite the bullet and borrow 10,000 yuan from South Manager. Although Zhang Nan lent him money, he began to doubt the purity of Baoliang's love, and their relationship reached an impasse. Bao Liang lost his original job. In order to make a living, he worked very tired in the car wash factory. He was very ill and almost died. Under the careful care of Feifei, Baoliang gradually recovered and found a job as a receptionist at the front desk of the hotel. After meeting Zhang Nan again, their love became hot again. Baoliang, who is happy, is very sad to find that Feifei has been contracted by others to treat her mother. In order to help Feifei, Bao Liang went to the subway station to beg. Finally, as a last resort, he had to borrow 50,000 yuan from Zhang Nan who suspected that Bao Liang was asking for money with her. Just when Bao Liang vowed that he was sincere, Nan saw the intimate photos of Bao Liang and Miao Miao in the little girl's room. She was very angry and left quietly. Liu Cunliang and Chen Li bought fifteen lottery tickets, and Baoliang helped them scrape out a first prize, but Chen Li ran away alone. A few days later, Bao Liang returned to his hometown Jianning, and the two brothers wanted to file a lawsuit for the lottery. Both sides asked Bao Liang to testify in court. Baoliang once again felt the fragility of human nature.

After many hardships, Bao Liang finally found his sister in Fushui, but his efforts to reconcile his sister with his father failed, and he himself was expelled from the unit because of long-term absenteeism. In order to cooperate with the public security organs to solve all three gun cases, Bao Liang came to Fushui again. In an accidental fight, Bao Liang personally killed all three shots. Bao Liang, who became a hero, was not only accepted by his original unit, but also forgiven by his father. His brother-in-law, Hu Quan, was sentenced to life imprisonment, and his sick sister was also sentenced to five years' imprisonment. Bao Liang adopted his sister's son Lei Lei. In order to raise and take care of Lei Lei, he even worked as a living sculpture in the night market square. One night, he met Zhang Nan by accident, and she already had another lover. Zhang Nan looked at the sculpture he played, said "This is a real person" to his partner, and drifted away, leaving Bao Liang with a broken heart and two lines of clear tears. My sister was released on medical parole because she was seriously ill. Baoliang should treat her sister and take care of Gaga. She was as busy as a bee and had a quarrel with her lover Laoqiu over Feifei. In an emergency, my father sent Bao a life-saving 50,000 yuan. But my sister finally died of a serious illness. Baoliang divided her sister's ashes into two parts, one with her mother and the other with her hometown, and scattered them on the banks of the Jian River where the sunset was about to set. 2 1 year-old Bao Liang still has an indelible tear in the corner of his eye, but his face shows a calm smile. He took Gaga's hand and walked down the hill. Under the hillside is the yard where Bao Liang lived as a child, and a wisp of smoke rises faintly in the yard.
