In the twenty-sixth year of the Republic of China, Su Wanying found a dusty box of film in the attic of her old house. The moment the film was rotated, she quietly fell into a strange time and space. The streets here seem familiar, but they have the absurdity and warmth of anime scenes - the nursery rhymes in the wartime countryside hide the innocent code of "Chibi Maruko-chan", the neon lights of the ballrooms of the Republic of China reflect the obscure guardianship of "Sailor Moon", and the deep alleys of old Shanghai hide the passionate metaphor of "Slam Dunk".
Each dimension travel is intertwined with the memories of the old time. In the dungeon, she meets "fellow travelers" with different personalities, including a taciturn mysterious scholar and a smart and cunning newsboy girl. They work together to solve the mystery of the Republic of China adapted from the animation, and find their way back between the flames of war and warmth. From being at a loss at first, Su Wanying gradually draws strength from the implicit bond, but finds that behind every dimensional mirror, there is a secret past related to reality, and her journey may be to make up for a regret that has been dusted by time.
