Rosemary Woodhouse and her struggling-actor husband Guy are thrilled to move into the Bramford, a sought-after Manhattan apartment building prized for its Victorian details and gargoyled facade. Yet as they learn of a darker side to the building's history—and become acquainted with their overly attentive neighbors, the Castevets—unspoken tensions enter into the young couples' relationship. Matters improve when Guy lands a major role, and Rosemary at last becomes pregnant. But as her pregnancy takes frightening turns, Rosemary begins to question if her neighbors' heightened interest is strictly innocent, or if their motivations—and those of Guy himself—portend terrifying consequences for her, and her unborn child. Is Rosemary "...going mad, or going sane"?
