When 10-year-old Aurora needs help killing the monster she believes ate her family, she hires her hit man neighbor (Mads Mikkelsen). Suspecting the girl's 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 inventive feature directorial debut from creator Bryan Fuller.
