In the urban "Mirror City" made of holographic mirrors, Lin Mo, a "scavenger" who has been deprived of his memory, clears away the digital detritus of the city day after day. An unexpected touch awakened fragments of broken memories in his mind - sunshine, waves and a girl's laughter. In order to recover his lost identity and the concealed truth, he must fight against the invisible eyes that control everything in the labyrinth constructed by the ubiquitous surveillance and lies of the "intelligent brain", and embark on a journey destined to be lonely and dangerous.
