A modern gold-medal maternity matron time-travels to the 1980s, becoming the tragic Yao Shula. Just as her mother passes away, her father Yao Zhiqiang insists on marrying her mother's apprentice Song Yuling. Yao Shula creates a ruckus at the wedding banquet, protects her younger siblings, and reclaims her mother's property and bereavement allowance. Facing her unfeeling father and troublesome stepmother, she also unexpectedly takes in Lei Jingtian, the son of the county committee secretary. Relying on her extraordinary insight and courage, Yao Shula publicly demands justice at the machinery factory, refusing to be a dodder flower dependent on others. Seizing the opportunities of the era, she opens a table tennis (kangleqiu) stall and engages in the clothing business, juggling career advancement while safeguarding the growth of her younger siblings. Intertwined with everyday trivialities and the hustle and bustle of secular life, the eldest sister cuts through thorns and thistles, leading the children to forge a vibrant new life.
