In a future where memories can be read and archived, top memory archivist Ling Su, a man who has forgotten his past, is hired by a mysterious widow, Gu Lan, to discover the cause of death of her husband, the genius scientist Yan He. Ling Su dived into the depths of Yan He's broken memories. He thought it was just a routine emotional archeology, but unexpectedly discovered that there was a taboo project called "Ouroboros" hidden in the memory. As the investigation deepens, the firewall in Yan He's memory, Gu Lan's evasive words, and the strange fragments that keep flashing in his mind all lead Ling Su to a truth that is far more dangerous than death. Not only is he the solver of the puzzle, he becomes the puzzle itself.
