In Xinhai City, shrouded in neon and rain, the job of top "memory scavenger" Lin Mo is to accurately erase painful memories for customers. He is a master of craftsmanship, but he is haunted by a blank past - a recurring and broken dream about a silver pendant. When a mysterious woman named Anya appears with a seemingly innocuous request - to erase the "smell of dust after the rain" - Lin Mo's career and personal nightmare begin to intersect. This was no ordinary purge, but a carefully orchestrated awakening. As the investigation deepens, he discovers that his forgotten past is the key to maintaining the city's false peace. He must make the final choice between regaining the cruel truth and guarding the false peace.
