The Superintendent-General's press conference quickly descends into chaos after the Laughing Man's assassination threat. Kusanagi suspects that the Laughing Man has inserted a virus into the police units assigned to guard the event. As Section 9 members struggle to evacuate the Superintendent-General to safety, the anti-virus team at HQ races to develop a vaccine to protect against it. However, random civilians begin joining in the assassination attempt as well, without any sort of external influence. After escorting the Superintendent-General to safety and apprehending all of the assassins, the police are left wondering what caused dozens of completely unrelated people to attempt to murder a single man. After the immediate threat is averted, Aramaki orders Section 9 to open their own investigation into the Laughing Man case.
