Shen Mian is reborn back to 1990. In her past life, her identity was stolen by her twin sister, her value was sucked dry by her parents, and she was betrayed by a scum boyfriend and died miserably on the operating table. In this life, she resolutely gives up the supply and marketing cooperative's golden rice bowl in exchange for the old house left by her grandmother. Relying on the memory of her past life, she gets rich overnight through stock trading, joins hands with Lu Ye, the "waste king" despised by the Chen family, to hoard materials and lay out plans, waiting quietly for the arrival of the demolition wave. When the whole family bets all their family fortune following the scum boyfriend in stock trading, attempting to get rich overnight, Shen Mian watches coldly, waiting only for the moment the stock market crashes.
