In the future city "Mirror City" where "memory calibration" technology is used to eradicate all negative emotions, Lin Mo, a top memory calibrator, is troubled by a sad memory that does not belong to him. He seems to be erasing the pain of others, but in fact he is searching for the truth in his own mental labyrinth. When he discovers that behind the technology that maintains the city's "happiness" lies a shocking scam about identity, freedom, and truth, he must choose between false tranquility and the cruel truth. What he wants to fight against is not only the impregnable urban system, but also his own past that has been tampered with.
