In a future city where "amnesia" is spreading, memories will be stripped away from patients and crystallized into "memory fragments" scattered in ruins. Ling Chen, the former "memory hunter", returned to the crisis-ridden quarantine area in order to find the last memory of his deceased sister. There, he met the mysterious woman Ye Tong, whose purpose seemed to surprisingly coincide with Ling Chen's. The two are forced to form a fragile alliance in a ghost town filled with other people's memories. As the truth approaches, they realize that they are not only looking for fragments of the past, but also a cruel secret about memory and existence that can subvert the entire world's perception.
