In a future where amnesia is rampant, human memories can be extracted, stored, and even traded. Lin Mo, a top "memory weaver", makes a living by repairing the broken memories of others, but seals up his most painful past. During a routine mission, he accidentally intercepted an encrypted memory fragment that did not belong to anyone. When he dived into the abyss of this memory, what he saw was a covered-up murder, and the clues pointed to the "Ark Group", the giant that controls memory technology, and his sister who had been missing for many years. In order to pursue the truth, Lin Mo must sail in the vast sea of oblivion and set foot on his own island of memory, which is full of dangers. What he will face is not only the black hand of power, but also the truth buried by his own hands that can subvert everything.
