Way back when...

An outbreak of an unknown disease accures in Zootopia, Ex Officer Nicholas P. Wilde is one of the last remaining few agents of the Division's first wave, a sleeper agent unit that was called into action soon after the outbreak of an Night howler like patogen. He didn't want to be in the unit, but he didn't have a choice.

(Disclaimer: this is loosely based on the universe of Zootopia and The Division game series)
