Twenty-two-year-old Lin Yiyou grew up in a northern immigrant family in Chengzhong Village, Shenzhen. Her grandparents were over seventy years old and worked hard to make a living in a green plant and flower shop. Her father died in the line of duty in her early years, and her mother still cared about the Lin family after she remarried. Lin Yiyou followed the example of her police father since she was a child and worked hard to get a public security position. On the day she passed the interview, the whole family was filled with joy and sorrow. They were happy that she had fulfilled her childhood dream, but they were full of regrets because of the lack of her father. She took a suburban bus alone to visit her father in Beishan Cemetery. On the way, she met Ren Zhiyuan, a boy of the same age, and their brief encounter left a superficial impression. After returning home, the family stayed at the flower shop and stayed together day and night. Their daily life was full of fireworks and warmth, hiding their longing for her father. After the induction training, Lin Yiyou and Ren Zhiyuan became colleagues in the police station. They got along day and night and developed an ambiguous relationship. In the blink of an eye, the sweet days were hit hard: her grandmother died of a serious illness, and rumors circulated for many years that her father had died due to drugs. In order to find out the truth about his father's sacrifice and comfort his grandmother's soul, Lin Yiyou, under the arrangement of his direct superior and his father's former master Xiang Weimin, pretended to be a rebel policeman and sneaked into the border drug cartel to undercover. The truth was concealed from all relatives, friends, and lovers. Ren Zhiyuan fell deeply into the pain of betrayal, lost his cynical nature as a rich second generation, and secretly traced her whereabouts alone; his younger brother Lin Yiyang stayed at home to take care of his elderly grandfather and comfort his divorced mother, while following the Internet cable Suo Yuan goes to the border to look for his sister; drug trafficking leader Lai Muye is about the same age as Lin Yiyou, and knows that Lin's father sacrificed his life to save him back then. While he is attracted by Lin Yiyou's tenacity and kindness, and falls in love with her, he repeatedly tests and doubts her true position, struggling in the pull of love and hate. In the end, Lin Yiyou relied on forbearance and wisdom to cooperate with the police to destroy the cross-border drug trafficking gang, clear his father's name, and complete the persistence and redemption of two generations of police officers.
