The story begins with Montressor narrating that Fortunato has hurt him. Even worse, Fortunato has insulted him. Thus, he must get his vengeance.
During the carnival season, Montresor, wearing a mask of black silk, approaches Fortunato. He tells Fortunato that he has acquired something that could pass for Amontillado, a light Spanish sherry.
Fortunato begins to cough. Montressor keeps offering to bring Fortunato back home, but Fortunato refuses. Instead, he accepts wine as the antidote to his cough.
The men continue to explore the deep vaults, which are full of the dead bodies of the Montresor family.
The men walk into a crypt, where human bones decorate three of the four walls. The bones from the fourth wall have been thrown down on the ground. On the exposed wall is a small recess, where Montresor tells Fortunato that the Amontillado is being stored.
