This adaptation of the "Sabrina the Teenage Witch" tale is a dark coming-of-age story that traffics in horror and the occult. In the reimagined origin story, Sabrina Spellman wrestles to reconcile her dual nature -- half-witch, half-mortal -- while standing against the evil forces that threaten her, her family -- including aunts Hilda and Zelda -- and the daylight world humans inhabit. Kiernan Shipka ("Mad Men") leads the cast in the titular role of the show that is based on a comic series of the same name.
