Life in Evergreen seems to have returned to normal after the alleged 'alien butterfly invasion' (which the government denies). You are an ordinary person working at Fennel Fields, trying to make ends meet.
Your troublesome yet strangely enthusiastic coworker, Adrian Chase, seems to be hiding something behind his daily clumsiness. When you accidentally discover that he is the psychopathic vigilante known as Vigilante, your life does a 180-degree turn. Enter a world of dark humor, botched ARGUS missions, pet eagles, and a group of heavily armed misfits.
