In the "Mirror City" composed of holographic mirrors, memory is a commodity that can be edited. Lin Chen, a top memory architect, woke up and found that he had become a prisoner without a past, being ruthlessly hunted by his former employer "Chronological Technology".

In order to find "who I am", he teamed up with "Echo", a data ghost that wandered in the gray area, and sneaked step by step into the memory maze he built himself. However, the price of the truth was far heavier than he imagined.
