"Inheritance in the Family" tells the story of the conflicts that arise between the two couples, Zheng Jiahao, Ma Qingmei, Zheng Meili, and He Zhihong, after the death of their father, Zheng Shuxuan, over the inheritance. They unexpectedly discover that their father had written a will six months prior, leaving the only asset—a house worth tens of thousands—to a woman named Ge Chunxiu. In order to claim sole ownership of their father's house, He Zhihong and Zheng Meili stage a divorce and He Zhihong becomes the homeowner. Ma Qingmei's family, facing financial difficulties, decides to move into the father's house and live with Zheng Meili. Living under the same roof, conflicts arise between the sisters-in-law. Zheng Jiahao, disgusted by the chaos, would rather give up the house. Ma Qingmei personally goes to Kunming to bring back Ge Chunxiu. After Ma Liang dies, Ma Qingmei and her brother, Ma Dahai, grow apart due to the inheritance. With Ma's father owing a large debt, Ma Dahai wants to legally avoid it, but Ma Qingmei cannot bear it on her conscience and ultimately chooses to inherit the "inheritance" and take on her father's debt. After Ge Chunxiu falls terminally ill, a friend of Zheng Shuxuan informs Zheng Jiahao of a shocking secret about Zheng Meili's identity... In the face of inheritance, some are consumed by greed, winning money but losing family and love, while others show great compassion and never abandon each other, supporting one another.
