In the "Floating Dream City" where memories can be extracted, edited and traded, Lin Mo, a top memory restorer, works with broken memories all day long in order to cure his sister who suffers from "white memory syndrome". A seemingly simple commission involved him in a huge conspiracy. The client asked to erase a trivial memory about the missing pendant, but deep in Lin Mo's memory, he glimpsed the afterimage of fear and a blurry man's face that should not exist. In order to pursue the truth and find hope to cure his sister, Lin Mo embarked on a dangerous journey. He will discover that the prosperity of this city is based on the tampered past, and he himself is just an island of memory floating in the sea of oblivion.
