Ginoza and Akane, along with the Enforcers, are brought in to investigate a death caused by a Drone at a Drone manufacturing plant. When the Psycho-Pass of the entire staff checks out, they question whether it was an accident or possibly murder.

Unit One has begun to grasp the truth behind the incidents following each other like a line of falling dominoes and team up with the SAD to continue their investigation. Arata guards the governor, who is at risk of being targeted again, while Kei organizes a sting using Kisaragi as bait. When he arrives at the appointed meeting place, however, he finds Shizuka Homura waiting for him.
