In the future city "New Arc" where memories can be traded and deleted, the top "memory stalker" Ling Chen accepted a strange commission: to retrieve the forcibly deleted memory of a woman who fell into a deep coma. This is not a simple recovery, but a confrontation with time, technology and a huge shadow. As the investigation deepens, Ling Chen discovers that this erased memory fragment not only hides secrets that can subvert the order of the entire city, but also has a fatal intersection with a key past that he sold many years ago in order to survive. In the whirlpool of truth, he not only wants to save his client, but also find himself lost in the sea of oblivion.
