In the 1980s, Su Li and her gravely ill son are reborn back to the day of his leukemia diagnosis. In her past life, she was schemed against by her factory director husband Song Yanshen and their lodging widowed sister-in-law Chu Qing, exhausting their savings, tragically losing her beloved son, and dying with lingering resentment. After rebirth, Su Li is clear-headed and decisive, swearing to protect her son's lifesaving money at all costs and decisively cutting off the misplaced marriage. Relying on her exceptional dance skills, she tests into the cultural troupe, earning money to treat her son while exposing Chu Qing's greedy plots and uncovering Song Yanshen's malfeasance and corruption. In the end, the villains are brought to justice, and Su Li takes her son to break free from hardship, welcoming a stable new life in the spring breeze of the eighties.
