The story centers around an unnamed narrator who chooses to spend the night in the remote Lorraine Castle. The narrator will rest in a room said to be haunted; in an effort to disprove the various legends surrounding it. Despite ominous warnings from the three infirm elderly people who reside there, he ascends to the "Red Room" to begin his night's rest.

While in the room, he is gripped by an inexplicable feeling of dread. As he tries to combat his fear, a series of events drive him into an outright panic. He begins to thrash at perceived phantoms until he hits his head and falls unconscious.

The next morning, he is awoken by the three occupants of the castle. When they attempt to relate local myths to explain the haunting, the narrator responds that it was merely his fear, "Fear that will not have light nor sound," that caused his reaction.
