In the future city "Xinhai City" where memories can be extracted, stored and traded, Lin Mo, a top memory organizer, is like a lonely lighthouse keeper, wandering among the broken memories of others. He is calm and restrained, and makes a living by repairing the memories of others, but deliberately keeps his own past dusty. One day, a mysterious woman named Su Qing brought a memory chip full of paradoxes - in the reflection of the sun and beach, another face of despair was reflected. This commission was like a boulder thrown into stagnant water. It not only involved Lin Mo in a huge conspiracy that could subvert the entire city's order, but also forced him to face the forgotten summer that he had been avoiding.
