For as long as residents can remember, the housing projects of Chicago's Cabrini Green neighborhood were terrorized by a word-of-mouth ghost story about a supernatural killer with a hook for a hand, easily summoned by those daring to repeat his name five times into a mirror. In present day, a decade after the last of the Cabrini towers were torn down, visual artist Anthony McCoy (Yahya Abdul-Mateen II; HBO's Watchmen, Us) and his girlfriend, gallery director Brianna Cartwright (Teyonah Parris; If Beale Street Could Talk, The Photograph), move into a luxury loft condo in Cabrini, now gentrified beyond recognition and inhabited by upwardly mobile millennials.
