Lin Yan, a professor of criminal psychology, has a disabled left hand, but there is a tampered memory hidden in his body. When he reunited with the hacker girl Bailu, a live broadcast suicide case revealed a bloody conspiracy that had been buried for 33 years in Kirigawa City - 66 children in the welfare home were buried in the flames, but he and she were the only ones to survive.
Corpses marked by gears, secret rooms with timed detonations, dead souls forged by AI... The mastermind behind the scenes, the "Clockmaker," provoked the police with perfect crimes. In Bailu's computer, there are death files of the murderer's parents.
