When Aurora needs help killing the monster she believes ate her family, she procures his services. Suspecting that her parents may have fallen victim to hit men gunning for him, Aurora's neighbor guiltily takes the job. To protect Aurora, he'll need to contend with an onslaught of assassins, a mysterious associate with killer heels (Sigourney Weaver), and accept that some monsters are real in this fantastical and wickedly inventive feature directorial debut from visionary creator Bryan Fuller.
