In Xinhang City, memories can be read, woven and sold. "Memory Weaver" Lin Chuan, a truth-seeker who can dive into the deep sea of other people's consciousness, has been with broken souls and false pasts all day long, until his own past has become a fog. A seemingly ordinary suicide case of a technology giant plunged him into a whirlpool from which he could not turn back. Suman, the daughter of the deceased, firmly believes that her father was murdered, and the only clue is a tampered dying memory. When Lin Chuan dived into the abyss, what he stared at was not only the secret of the deceased, but also an echo closely connected with his forgotten past. The truth may be more frightening than death.
