In A Reflection of Fear a young woman, Marguerite (Sondra Locke), cloistered in a turn-of-the-century Victorian dream-world by her mother, vies for the attention of her visiting dad, Michael (Robert Shaw), both conventionally and sexually, in hopes that she'll get to live with him. Her plans are complicated by a series of murders that may or may not be by Marguerite or her eerie life-size doll Aaron. The perpetrator moves around the estate through secret passageways. The first victims are Marguerite 's mother and grandma. While the investigation is under way, a local boy tries to woo the girl, but whenever he gets too close, the girl lashes out in unpredictable ways. Meanwhile Michael's fiancée, Anne (Sally Kellerman), becomes suspicious of Marguerite and what she understandably sees as Marguerite's creepy competitions for her dad's love. Anne's initial efforts to befriend Michael's daughter turn into exasperation and disgust. As the situation spirals out of control, the long-absent father is forced to confront Marguerite 's twisted personality and upbringing.
