In the 1990s, the widow Xie Yujin (played by Li Mingqi) lived with her children in an old courtyard house: the eldest son Bai Erhei (played by He Bing) was a simple and honest man and married the stubborn Chen Xiaona (played by Niu Li). Chen Xiaona lost her fertility due to a car accident, and became a big concern for Xie Yujin, who longed for sunshine. As a result, Chen Xiaona was full of doubts and family conflicts all day long; the second son Bai Jie (played by Zhan Weihua) beheaded the gang boss Zhou Long (played by An Zehao) and was sentenced to ten years in prison. After he was released from prison, Bai Jie wanted to be a good person, but Zhou Long tried to frame him repeatedly, making his family worry about him; his daughter Bai Yu (played by Li Ying) is a kindergarten teacher. She is straightforward and quick. She couldn't stand the behavior of her sister-in-law Chen Xiaona, so she always opposed her. Bai Erhei meets Liu Dan (Chen Na), Pan Panpan (Gao Yaoping) and their mother and daughter who have advanced lung cancer. They tried everything to help them, but Chen Xiaona misunderstood and the two divorced. After the divorce, Chen Xiaona's relationship with psychologist Li Shaoyang heated up. Unexpectedly, Li Shaoyang turned out to be Xie Yujin's youngest son who had been separated for many years. Chen Xiaona broke up, reconciled with Erhei, and adopted a helpless daughter Pan Pan. Bai Jie sneaked into the Zhou Long drug cartel, helped the police destroy the den in one fell swoop, and won Xiao Juan's heart. After many twists and turns, the family in the yard was happy.
