Five years ago, Chen Fang, the commanding leader of the underworld, lost both her husband and son in a single night. She subsequently retired from the underworld and made a living selling steamed buns. Five years later, her only daughter-in-law, Shen Rou, was humiliated by Zhao Chuan, the young master of the Zhao family, and his accomplices at her birthday banquet. Driven to despair, Shen Rou jumped from a building and fell into a coma, hovering between life and death. To save her daughter-in-law, Chen Fang is forced to return to the underworld, unleashing once more the formidable power she once wielded as its commanding leader. She searches for Ling Xue, the founder of Qisheng Biotech, the key person who can awaken Shen Rou. Meanwhile, she systematically purges her enemies within Huasheng Group, carefully advancing her plans step by step. Ultimately, Chen Fang brings all her enemies to justice through the rule of law. Shen Rou awakens and inherits the family business, while Chen Fang returns to her humble street-stall life, embracing her family amid the warmth of everyday life and finally settling the old scores of the underworld.
