Rosemary Woodhouse & her struggling actor-husb&, Guy, move into the Bramford, an old New York City apartment building with an ominous reputation & only elderly residents. Neighbours Roman & Minnie Castavet soon come nosing around to welcome them; despite Rosemary`s reservations about their eccentricity & the weird noises that she keeps hearing, her husband starts spending time with them. Shortly after Guy lands a plum Broadway role, Rosemary becomes pregnant, & the Castavets start taking a special interest in her welfare. As the sickened Rosemary becomes increasingly isolated, she begins to suspect that the Castavets` circle is not what it seems.
