Li Xiao, a modern working woman, suffered a cognitive collapse due to her mother's dependence on her father before she died of cancer, and accidentally traveled back to 1972. She tried to prevent her mother Pan Yongge from marrying her "Phoenix Man" father Li Baohua, but in the wave of Liuzhou's industrial development, she witnessed the truth about her parents' relationship from "basketball bonding" to "shared suffering in the workshop." She discovered that her father was not a burden that only sucked blood, but the most solid chessboard behind her mother's "strong chess piece".
