In the "Old Rain City" where it rains cold acid rain all day long, memory is the most expensive commodity and the most deadly weapon.
Lin Chuan, a "memory stealer" who lives in the "sinking area" at the bottom of the city, survives in the darkness with his skillful hands that can sneak into other people's memories. His only belief is to cure his sister Lin Mo's fading memory.
In order to get a sky-high reward for saving his sister, he took on the most dangerous commission - to crack an encrypted memory crystal from a forbidden place. However, when he opened Pandora's box, what was released was not wealth, but a shocking lie that could subvert the order of the entire city.
It turns out that this city's eternal myth is based on a living prison of thought.
Overnight, Lin Chuan went from an unnoticed thief to the number one public enemy of the city's dominant "eternal life technology". Ruthless prosecutors, cunning black marketeers, resistance organizations with unknown intentions... An invisible web is closing in on him.
In order to survive, for his sister, and to find the truth that was deprived of him, he must put on a hood, walk between neon and shadows, and use stolen memories to declare war on this hypocritical world.
But as he gets closer to the core of the truth step by step, he discovers that what he has to fight may be far more than just a huge technological empire.
