In the future city "Xincui City", memory erasure technology has become the norm. Lin Mo, an elite memory archivist, is responsible for experiencing and archiving clients' discarded memory fragments. He is like an isolated island, carrying the past of countless others, but knowing nothing about his own past. During a routine job, a warm memory about a red kite that did not belong to any customer flooded into his mind, triggering the highest alarm in the system. This false "reverberation" was like a key, forcing Lin Mo to explore his erased identity and the shocking conspiracy hidden behind this "forgotten city". He will discover that forgetfulness is not a gift, but a more cruel form of imprisonment.
