In the near future where memories can be accurately deleted, Lin Mo is the best memory planner of "Wangchuan Technology". With scalpel-like precision, he peels away the painful past for his clients and calls himself the scavenger of souls. However, during a routine operation, the memory fragments of a mysterious female client unexpectedly triggered his dusty past - a memory about his sister's death that should have been clear and cracked began to appear. A metal dragonfly symbol that should not exist is like a key, opening the door to a maze of truth and lies. Lin Mo is forced to embark on a journey to find his true past, only to find that he is floating in a sea of oblivion constructed by the will of others, and his only foothold may be just an isolated island called "memory".
