Shen Zhiwei, a woman who lived a life of servitude and betrayal, dies at the hands of her husband Chen Weidong and his mistress Li Man, who conspired to seize her family's property. In a twist of fate, she awakens in 1975, moments before Chen Weidong's public promotion ceremony. Armed with memories of her past suffering, she publicly exposes Chen Weidong's adultery, embezzlement of military supplies, and the fact that Li Man's child is actually his illegitimate son. Her accusations are backed by a detailed ledger of illicit transactions, leading to the immediate isolation and investigation of Chen Weidong and Li Man by the Military Discipline Inspection Commission, represented by Gu Yanzhou.
Gu Yanzhou, who in her previous life had helped uncover the truth after her death, now offers Shen Zhiwei protection and support. She moves into his residence temporarily, where a cautious romance begins to develop between them. Shen Zhiwei also discovers that she possesses a spiritual spring space linked to a jade bracelet, which allows her to store items and purify water with healing properties. Using this advantage, she rescues her father, Shen Guodong, a chief engineer facing false accusations and persecution by factory officials Li Jianye and Wang Qiang, who seek to steal his technical research.
Shen Zhiwei systematically dismantles the schemes of her enemies. She empties her father's house of valuable research materials and family treasures into her spiritual space before the Revolutionary Committee can ransack it. She confronts Chen Weidong's family, including her abusive mother-in-law Zhang Chunfang and stepson Chen Zihao, reclaiming her property and cutting ties with them completely. She also exposes Director Wang's history of theft and harassment, leading to his arrest.
The core conflict centers on Shen Zhiwei's quest for justice and her family's survival against those who exploited her in her past life. She uses her knowledge of future events to anticipate the moves of Li Man, who appears to have foresight similar to her own. Shen Zhiwei collaborates with Gu Yanzhou to investigate Li Man's secrets while navigating the complex political landscape of the military and factory systems. She successfully negotiates a favorable divorce settlement, securing the house and financial compensation from Chen Weidong, and protects her father's research from being confiscated by corrupt factory officials. The story follows her transformation from a victim into a powerful figure who controls her own destiny, supported by her growing relationship with Gu Yanzhou.
