Chen Jiao, a survivor of the apocalypse who died in a final explosion to protect her supplies, awakens in the body of a woman with the same name in a historical famine era. The original owner was known for her vicious personality, having abused her mother-in-law Wu Guilan and her twin children, Lu Lingyang and Lu Yaling. She also squandered the family's resources on Chen Haoyu, a manipulative educated youth, and his friend Zhang Fangfang. Upon regaining consciousness, Chen Jiao discovers she has retained her wood-type abilities and a spatial dimension containing food, water, and supplies from her previous life. She immediately begins to reform her image, cooking nutritious meals for her family and attempting to build trust with the terrified mother-in-law and her suspicious son.
Lu Lingyang, a four-year-old boy with the ability to hear Chen Jiao's inner thoughts, remains deeply hostile toward her. He believes her sudden kindness is a ploy to fatten the children up before selling them to Chen Haoyu, who desires a luxury watch. Chen Jiao, aware of his suspicions through her own internal monologue, decides to prove her sincerity through actions rather than words. She confronts Chen Haoyu and Zhang Fangfang in public, exposing their exploitation of the original owner by producing handwritten IOUs that Chen Haoyu had foolishly written to appear noble. The village women, incensed by the educated youth's greed, force the couple to repay the debts within three days.
The family's situation shifts dramatically when a military vehicle arrives, bringing news that Chen Jiao's husband, Lu Zhengxu, has returned from a mission in a vegetative state after sustaining severe head injuries. The military provides the family with three thousand yuan in savings, five hundred yuan from comrades, and a monthly allowance, securing their financial future. Chen Jiao decides to stay and care for Lu Zhengxu, hoping to use her medical knowledge and spiritual energy to heal him. Her in-laws, particularly the third uncle, attempt to shirk their responsibilities, claiming poverty, but the second uncle and the village leader support Chen Jiao. As she settles into her new role, Chen Jiao plans to prepare for the upcoming college entrance examination, aiming to build a stable and independent life for herself and the children, while navigating the complex dynamics of her new family and the lingering distrust of her stepson.
