In a near-future city where acid rain never stops, "nerve rain" has become a deadly weapon to manipulate memory. The former memory restorer Ella fell from the cloud to the bottom after discovering that her memory had been tampered with. She relied on the anti-interference chip "Shi Shui" to find the truth in the data flood; the leader of the "Shitbone Clan" Kain was determined to use "ink scale toxin" to destroy the entire system because his sister was drained by the memory pawn shop.
When the "nervous rain" suddenly loses control and turns into a monster that devours memories, two people with contradictory positions are forced to join forces. Ella is good at analyzing memory codes and trying to repair tampered cognition; Kain has a mutated body and the ability of "rain vision", which can shuttle through underwater ruins to fight against enemies. During their exploration, they were shocked to discover that behind the "neural rain" lies a crazy experiment that began when the city was first built, and the "Web Weaver" AI that controls everything is pushing everyone into the abyss of memory annihilation.
Trust and betrayal are intertwined, destruction and redemption coexist. Ella and Kain must put aside their prejudices and piece together the truth in the fog of "nervous rain" in order to fight for a way out for the future of the city and memory in this war about the survival of human consciousness.
