On the isolated island of Ajsselburg, memories are digital assets that can be read, stored and deleted. Lin Feng, an elite memory archivist, accidentally discovered a "ghost chip" that was supposed to be formatted during a routine maintenance. In the chip, a vivid memory that belongs to no one - sunshine, waves and a girl wearing a red scarf - completely overturns his orderly world. In order to pursue the truth, Lin Feng embarked on a dangerous path. Under ubiquitous surveillance and pursued by the "Guardians of Order," he must piece together a forgotten history while confronting the blanks of his own past. He will discover that this island of memory is built on a sea of lies called forgetfulness.
