In the "Mirror City" where neon lights and rain intertwine, memories can be read, woven and even erased. Lin Zhou, the former top "Dream Weaver", went into self-exile due to a failed mission and ran a humble memory repair shop. A bizarre secret room murder case brought him back into the vortex: Technology giant Chen Mo died in his own mansion in the sky, and his memory of the hour before his death was precisely and completely erased. Captain Zhao Li, an old acquaintance who was ordered to investigate the case, had to turn to Lin Zhou for help. While sneaking into the maze of broken memories of the deceased, Lin Zhou was horrified to discover that in the depths of this blank memory, there were deadly echoes related to his lost past. He must navigate the tightrope of truth and danger, otherwise, he and the city's crimes and punishments will be buried together.
