The unnamed narrator describes the qualities of Ligeia, a beautiful, passionate and intellectual woman, raven-haired and dark-eyed, that he thinks he remembers meeting "in some large, old decaying city near the Rhine." He is unable to recall anything about the history of Ligeia, including her family's name, but remembers her beautiful appearance. Her beauty, however, is not conventional. He describes her as emaciated, with some "strangeness." He describes her face in detail, from her "faultless" forehead to the "divine orbs" of her eyes. They marry, and Ligeia impresses her husband with her immense knowledge of physical and mathematical science, and her proficiency in classical languages. She begins to show her husband her knowledge of metaphysical and "forbidden" wisdom. After an unspecified length of time Ligeia becomes ill, struggles internally with human mortality, and ultimately dies. The narrator, grief-stricken, buys and refurbishes an abbey in England. He soon enters into a loveless marriage with "the fair-haired and blue-eyed Lady Rowena Trevanion, of Tremaine." In the second month of the marriage, Rowena begins to suffer from worsening fever and anxiety. One night, when she is about to faint, the narrator pours her a goblet of wine. Drugged with opium, he sees (or thinks he sees) drops of "a brilliant and ruby colored fluid" fall into the goblet. Her condition rapidly worsens, and a few days later she dies and her body is wrapped for burial. As the narrator keeps vigil overnight, he notices a brief return of color to Rowena's cheeks. She repeatedly shows signs of reviving, before relapsing into apparent death. As he attempts resuscitation, the revivals become progressively stronger, but the relapses more final. As dawn breaks, and the narrator is sitting emotionally exhausted from the night's struggle, the shrouded body revives once more, stands and walks into the middle of the room. When he touches the figure, its head bandages fall away to reveal masses of raven hair and dark eyes: Rowena has transformed into Ligeia. Sur le bord du Rhin, le narrateur rencontre et épouse Ligeia, une jeune noble d'une grande beauté et aux connaissances immenses. Grande et mince, aux longs cheveux noirs ondulés, aux yeux noirs fendus, il émane d'elle une mystérieuse étrangeté. Ligeia tombe malade et meurt en laissant le narrateur au désespoir. Il se réfugie dans un ancien couvent anglais, et fait la connaissance d'une autre noble jeune fille, Lady Rowena de Trevanion, blonde aux yeux bleus, belle aussi mais très différente de sa première femme. Il l'épouse sans pouvoir oublier un instant Ligeia. Leur chambre de noce ressemble à une tombe. Lady Rowena est rapidement assaillie d'évènements étranges, surnaturels évoquant une maison hantée. Épuisée par son angoisse, peu soutenue par un mari opiomane qui ne l'aime pas, elle tombe malade et meurt. Dans la chambre mortuaire, le narrateur se retrouve seul à veiller son épouse défunte. Au milieu de la nuit, de nombreux signes montrent que le cadavre revit puis que la mort le reprend. Terrorisé, il assiste à ces résurrections successives jusqu'à ce qu'au petit matin, le cadavre se lève du lit mortuaire entouré de son suaire. Écartant le drap, il se rend compte qu'il a devant les yeux une jeune femme grande, aux yeux et aux longs cheveux noirs, Ligeia.
