During the war in the old capital, artillery fire was approaching. Pei Zhiheng, the administrator of the National Library, was ordered to transfer precious classics to the underground library, but he was troubled by the cataloging problem of the fragmented pages of the original books. By chance, he met Du Ruo, a blind school doctor, a woman who could "read" paper and ink with her fingertips, and became the unexpected guardian of the library.
In the dark library, he cataloged and she stored her memories. As their fingertips touched, feelings and beliefs grew together. The invaders' search was getting closer and closer, and sentries, interrogations, and pursuits followed one after another. They used "broken pages" as their secret code and guarded the fire of knowledge with their lives.
Until the desperate situation came, the two fought side by side against the enemy, and finally waited for a glimmer of light to break through the darkness. Those classics and love hidden in the darkness finally found their perfect home in the sunshine.
