In a near-future city where memories can be extracted, traded or even tampered with, Lin Zhao is a "memory recycler" who walks in gray areas. His job is to sneak into other people's memory fragments, repair the defects, or remove the stains. Until an unusual commission, he saw the figure of his sister who had been missing for three years in a criminal memory that had been deliberately erased.
When wanted, pursued and shadowed by the mysterious organization "Meng Yuan" at the same time, Lin Zhao discovered that his sister's disappearance was not an accident, but a shocking conspiracy about "consciousness immortality". In the confusion between memory and reality, he must uncover the layers of disguise.
But the truth is often crueler than memory. When memories can be forged, how can you determine who you are? When the past can be modified, are you still willing to pursue the truth?
