In an era when "fog" is coming and global amnesia is spreading, memory has become the most precious luxury. Lin Mo is a top "memory weaver". His job is to repair and reshape the clients' memories that are on the verge of being broken. Once, he accepted a commission from business tycoon Mr. Chen to restore the last memory of his deceased wife. However, during the weaving process, Lin Mo discovered a "paradox fragment" that should not exist - a detail that violated the logic of time and space. This tiny anomaly was like a lead, dragging him into a huge vortex of conspiracy. The intervention of the Memory Security Bureau and the pursuit of mysterious forces made Lin Mo realize that what he had touched was not only a person's past, but also the core secrets related to the truth of the "Mist" and the future of mankind. He must fight against the ocean of forgetfulness on the island of memory.
