Lin Wanwan in the 21st century woke up and became a rural military wife in the 1970s. She looked at the three thin children and felt extremely distressed, but found that she was full of strangers to them. Her mother-in-law, Zhang Guihua, is very picky and picky about her, but she also hides her longing for her son and longing for home. Food shortages, dilapidated houses, and rumors make every step extremely difficult. She uses modern knowledge to improve lives, warms her children with patience and love, and resolves disputes between sisters-in-law with wisdom. From the initial confusion and helplessness to the gradual integration, she established a deep mother-child friendship with the children. The eyes of the mother-in-law changed from scrutiny to trust, and the comments of the villagers changed from ridicule to admiration. She thought life would continue peacefully and warmly until a telegram broke the tranquility. Her husband Lu Zheng, who is far away on the front line, is about to return. The man she has never met but has the deepest bond with her. A strange yet familiar husband, a brand new home, a completely different wife. When the heroes return home, how will they face each other? Where will this military marriage go?
