Ningxia, a talented foreign language translator, was reborn in 1975 after an unexpected mall collapse and became an orphan girl with the same name. What surprised her even more was that the department store where she was killed in her previous life turned into a portable space and provided her with a wealth of supplies. In order to survive in this special era and hide the secrets of space, she used her foreign language talent to find a translation job at Xinhua Bookstore. By chance, she caught the attention of the stern military officer Lu Chuan with a confidential foreign language document. Lu Chuan was deeply attracted by Ning Xia's excellent language skills and mysterious temperament, and the two gradually developed feelings during their constant contact. Ningxia uses space materials to improve her life and helps Lu Chuan solve work problems, while Lu Chuan uses his own way to silently protect Ningxia and the cute twins she unexpectedly adopted. Facing challenges from life and doubts from others, they work together to overcome difficulties and grow together. In the end, Ningxia not only achieved success in her career, but also gained a happy love and a happy family, and composed a warm and touching sweet love song in that special era.
