Gu Shuang, the sole heir of the Gu family, spent years exploring and returned home low-key. At the wedding banquet of her father Gu Chengyue and Shen Wanqing, she was humiliated by her stepsister Xu Mingzhu, revealed her identity on the spot, and halted the wedding. After taking charge of the Gu family, she reorganized the internal affairs, provoking crazy revenge from Shen Wanqing and her daughter, facing a car accident and her father being kidnapped. Gu Shuang met Lin Shen, a strategist burdened with a family blood feud. The two joined forces to investigate, uncovered the old wrongful death case of Lin Jianguo from eight years ago, and rooted out the Golden Association, a transnational money-laundering organization hidden within the Gu family, along with the mastermind Chen Changqing. Placed in desperate straits with imprisonment and frozen assets, the two shared life and death, built a digital fund tracking network, and wiped out the dark forces at an international summit.
