In a collection of three macabre stories, the narrative begins with "Dr. Heidegger's Experiment," where two elderly friends, Dr. Carl Heidegger and Alex Medbourne, discover a miraculous fountain of youth in the doctor’s garden crypt. As they drink the water, they regain their youth and vitality but soon face the awful consequences of meddling with nature. The second tale, "Rappaccini's Daughter," centers on the tragic love story between Giovanni and Beatrice. Giovanni discovers that Beatrice, the daughter of a peculiar scientist, is confined to her home and garden, surrounded by poisonous plants that have made her toxic to other humans.

The final segment, "The House of the Seven Gables," follows Gerald Pyncheon, who returns to his ancestral home with his new bride Alice after twenty years. The mansion is steeped in dark history and curses tied to a mysterious hidden vault. Gerald's obsession with finding a long-lost family treasure soon stirs malevolent forces within the manor, affecting all who reside in it. These chilling episodes explore themes of obsession, forbidden love, and the dark side of human nature through supernatural and gothic elements, leading the audience through suspenseful and eerie experiences rooted in moralistic tales.
