Xiang Tian accidentally travels back to 1972, holding a five-layer supermarket space that can automatically restock. Intending to go to the countryside to tough it out until the college entrance examination, she instead marries Jing Yuchuan, an engineer at the steel rolling plant with a "son", to avoid a blind date arranged for going to the countryside. The two get their marriage license, move into a large compound, and while she uses her space to improve their life, submits articles, writes novels, and pursues her career, she and her stepson Jing Zhou team up to watch all sorts of neighborhood drama, living a lively and vibrant life in the seventies.
