In the future city "New Island" where memories can be extracted, traded and erased, Ling Chen, the top "memory hunter", makes a living by pursuing lost memories. He is calm and efficient, but he can't find his incomplete past. A mysterious commission breaks his numb life - an elegant woman named Yi Su pays a high price, just to find a "blank" memory, a record of "nothingness" itself. This seemingly absurd task drags Ling Chen into a huge vortex intertwined by top technology companies, underground memory black markets and forgotten ghosts. The closer he got to the truth, the more he discovered that the end of that blank memory was actually the starting point leading to his own burial.
