In the future city "New Huanjing" where memories can be read and woven, Lin Mo, a top memory organizer, exiled himself because he was unable to explore the blank memory of his wife's death. A difficult commission broke his peace: Technology giant Gu Yuan hired him to enter the memory of his daughter, Gu Xinci, who fell into a deep coma, and find out the truth behind her suicide attempt. When Lin Mo dived into that broken spiritual world full of symbols and defense mechanisms, he discovered that the girl's memory labyrinth not only hid a family's shocking secrets, but also had a strange resonance with his own dusty past. In order to save the girl and redeem himself, Lin Mo must hear the faint whisper from the abyss of memory before he is swallowed up by the abyss of memory.
