In the mirror city where neon lights and rain intertwine, memories can be surgically stripped away. Ling Su, the top memory stripper, personally erased his memory of his deceased wife and lived in a void without joy or sorrow. A seemingly ordinary commission involved him in a well-planned conspiracy. The traumatic memory that client Su Wan claimed to be stripped off turned out to be a false brand that had been artificially implanted. In order to find out the truth, Ling Su embarked on a dangerous journey. Not only does he have to fight against the mysterious organization implanted in his memory, but he also has to face the past that he has deliberately forgotten. The crimes and punishments that have been buried in the dust are swallowing him up completely with the echoes of the Mirror City.
