âIn 1927, southern belle Charlotte Hollis (Bette Davis) and lover John Mayhew (Bruce Dern) plan to elope during a party at the Hollis family's antebellum mansion in Ascension Parish, Louisiana. However, it turns out John is married to another woman. Charlotteâs father detests the affair, and to end it he intimidates John by telling him his wife visited the day before and he told her about the affair. To end the affair and return to his wife, John tells Charlotte he no longer loves her. Sometime in the evening John is brutally murdered. In the mansionâs summerhouse, he is decapitated with a meat cleaver and his hand severed. Charlotte discovers Johnâs mutilated body and is traumatized. She walks to where the party is taking place, her white dress covered with Johnâs blood. People assume Charlotte is the murderer. The story jumps to 1964. Charlotte is now an elderly, wealthy spinster, still living in the familyâs now decrepit plantation mansion. Also living in the mansion is Velma (Agnes Moorehead), Charlotteâs housekeeper. Charlotteâs father died the year following John Mayhewâs murder. He died believing his daughter murdered Mayhew. Charlotte believed her father killed Mayhew. The community assumed Charlotte murdered her lover, in a fit of rage after John called off their plans to elope and ended the relationship. The Louisiana Highway Commission plans to demolish the mansion to build a new highway through the property. Charlotte is vehemently against this. She ignores an eviction notice and refuses to vacate. She keeps the foreman (George Kennedy), his demolition crew, and the bulldozer away by shooting at them with a rifle. They temporarily give up and leave. Seeking help in her fight against the Highway Commission, Charlotte calls on Miriam (Olivia de Havilland), a poor cousin, who in childhood lived at the mansion with the Hollis family. Separately, Miriam renews her relationship with Drew Bayliss (Joseph Cotten), a local doctor who, after the Mayhew murder, broke off his relationship with Miriam. With Miriamâs arrival at the mansion, Charlotteâs sanity mysteriously starts to deteriorate. Charlotteâs nights are haunted by a harpsichord playing a melody Mayhew wrote for her, and by the appearance of Mayhewâs disembodied hand and head. Housekeeper Velma, suspecting that Miriam and Drew are after Charlotteâs money, seeks help from Mr. Willis (Cecil Kellaway), an insurance investigator who is still interested in the Mayhew murder, and who has visited Mayhewâs ailing widow, Jewel (Mary Astor). Miriam fires Velma, who later returns and discovers that Charlotte is being drugged. Miriam catches Velma trying to help Charlotte escape the house. The two argue at the top of the stairs. Velma tries to leave but Miriam smashes a chair over her head causing Velma to tumble down the stairs to her death. One night, a drugged Charlotte runs downstairs in the grip of a hallucination, believing John has returned to her. To drive Charlotte completely insane, Miriam and Drew trick Charlotte into shooting Drew with a gun loaded with blanks. Miriam helps Charlotte dispose of the supposedly dead Drew into a swamp. Charlotte returns to the mansion only to see the deceased Drew at the top of the stairs. This reduces Charlotte to whimpering madness. Now believing Charlotte completely insane and having locked her in her bedroom, Miriam and Drew walk into the garden to discuss their plan: to drive Charlotte insane so they can steal her money. Miriam also tells Drew that, back in 1927, she witnessed Mayhewâs wife Jewel murder her husband. Sheâs been using this information to blackmail Jewel for all these years, while also plotting to gain possession of Charlotteâs wealth. Charlotte overhears the entire conversation between Miriam and Drew. Charlotte moves toward a huge stone urn on the ledge of the balcony, almost directly over the plotting loversâ heads, and pushes it over towards Miriam and Drew. As Miriam embraces Drew she notices the urn being tipped and coming down on her and Drew, and also discovers Charlotte glaring at them. The look in Charlotteâs eyes tells Miriam the entire conversation was overheard. As she stands stunned at the sight of Charlotte, the massive stone urn crushes the two dead. The next morning the authorities drive Charlotte away, presumably to an insane asylum. Many neighbors and locals gather at the Hollis home to watch the spectacle, believing that crazy Charlotte has murdered again. In the car, insurance investigator Willis hands Charlotte an envelope from the now-dead Jewel Mayhew, who had a stroke after hearing of the previous nightâs incident. In the note, Jewel confesses to the murder of her husband, John Mayhew. As the authorities drive Charlotte away, she looks back at her beloved plantation, apparently for the last time.â
