The Stephen King multiverse is the setting for this psychological horror series that takes place in Castle Rock, Maine, which is a location familiar to fans of King's work. "Castle Rock" explores themes and worlds that unite King's canon, including the infamous Shawshank Prison. An anonymous phone call lures death-row attorney Henry Deaver back to Castle Rock. He is unsettled by his hometown, but he returns to help a sinister, mostly mute man being kept in a cage underneath Shawshank. Sissy Spacek and Bill Skarsgård, who starred in feature adaptations of King's "Carrie" and "It," respectively, are among the show's stars.
