Plot Summary:

Rosemary Woodhouse (Mia Farrow), the young wife of a struggling actor (John Cassavetes), is thrilled to find out she's pregnant. But the larger her belly grows, the more certain she becomes that her unborn child is in serious danger. Perhaps there's something sinister behind the odd enthusiasm her eccentric neighbors (Sidney Blackmer and Ruth Gordon, in an Oscar-winning performance) have for her welfare. Or perhaps it's all in her mind.
