In the "Shadowless City" where memories can be extracted, traded and deleted, Lin Chuan is a "memory scavenger" who makes a living by processing and reselling abandoned emotional fragments, and trying to retrieve a period of his erased childhood. A mysterious commission drew him into the whirlpool: the client asked him to sneak into a "blank memory" that belonged to no one and find a missing girl. When he went deep into the abyss of emptiness, he discovered that the truth of this memory was not only connected to the darkest secrets of the city, but also pointed to a past that he did not want to be remembered.
