When Chief Bogo, the Mayor, and other powerful figures suddenly fall ill, the city's balance shifts overnight. A provisional captain takes control of the ZPD, and a new mayor resurrects a buried chapter of Zootopia's history: a past epidemic blamed on birds, followed by their forced exile under a fragile agreement. As fear spreads and old prejudices resurface, Judy and Nick suspect the illness isn't an accident. Against orders and under the radar, they pursue a lead only Nick can access: someone with ties to the birds. What begins as a quiet investigation turns into a storm of power, lies, and a past determined to repeat itself.
