Carter, a weird fiction writer, meets with his close friend, Joel Manton, in a cemetery near an old, dilapidated house on Meadow Hill in the town of Arkham, Massachusetts. As the two sit upon a weathered tomb, Carter tells Manton the tale of an indescribable entity that allegedly haunts the house and surrounding area. He contends that because such an entity cannot be perceived by the five senses, it becomes impossible to quantify and accurately describe, thus earning itself the term unnamable. As the narration closes, this unnamable presence attacks both Carter and Manton. Both men survive and awaken later at St. Mary’s hospital. They suffer from various lacerations, including scarring from a large horn-shaped object and bruises in the shape of hoof-prints on their backs.
