In the new Kyoto of 2077, memory is no longer a private soul destination, but a commodity that can be read, repaired, and even traded. Lin Zhou, an independent "memory master" with superb skills but alienated heart, makes a living by repairing the broken memories of others.
An ordinary commission made him discover a "dark red scar" that should not exist in the childhood memories of a powerful man. This brand-like trace is like a key, opening the door to the abyss. Warnings, lies and fatal pursuits followed one after another, and Lin Zhou was forced from a bystander to become a fugitive hunted by the technology giant "Eternal Life Technology".
In order to survive and to find out the truth, he joined forces with the mysterious hacker "Night Owl" who wandered in the undercurrent of data. In the gap between neon and shadow, they discovered that hidden under the "scars" were stolen lives. When memories can be customized, does your life still belong to you?
Faced with the all-powerful corporate empire and his dusty past, Lin Zhou must make a choice: to forget in silence, or to scream to the city of eternal night the truth that can overturn the entire world before being completely erased.
