In a futuristic city soaked in neon and rain, memories can be repaired, cut or even erased like fabric. Wang Meng makes a living by repairing other people's traumatic memories, but he has never been able to mend the cracks in his own heart. When Su Wan, a talented violinist, walks into his clinic with a seemingly simple request - to erase the moment of her lover's death, Wang Meng is forced to confront the dual torture of his work ethics and the nightmares of his past. He discovered that some memories are like ghosts. Even if they are cut off, their echoes are enough to swallow everything. This is not only a game with memory, but also a profound exploration of human nature, love and sacrifice.
