A story about Shanghai citizens is told from the perspective of Feng Xiaoqin and Gu Qingyu, two sisters-in-law who work through their differences to grow closer in the quagmire of life.

It has been ten years since Feng Xiaoqin (Hai Qing) came to the Gu family while pregnant with child to become their new daughter-in-law. The family's eldest daughter, Gu Qingyu (Tong Yao), has always been wary of her and believes that Feng Xiaoqin has "ambition" written all over her face. Feng Xiaoqin urges her husband Gu Lei to borrow money from his twin sister Gu Qingyu so they can buy a house. Gu Qingyu cleverly evades the request by revealing her plan to buy a luxury house.

After Gu Lei dies unexpectedly, the conflicts between the two sisters-in-law continue to escalate. As a single mom, Feng Xiaoqin is desperate, yet the trials that she faces allows her to realize her true potential. Meanwhile, Gu Qingyu undergoes many changes that reshapes her perception towards life. From relentless confrontation to mutual understanding, the two women will bear the burdens of the family together no matter how hard the future is.
