During Carnival in Italy, Montresor runs into Fortunato, and offers to share a very nice bottle of Amontillado wine with him. However, this bottle is in his catacombs. It is late at night and Fortunato seems ill.
The narrator, Montresor, claims that Fortunato has gravely insulted him, and is plotting to get his revenge. Although, he doesn't tell the reader what Fortunato has done, he makes it known that it was unforgivable.
Montresor lures Fortunato down into the dark and eerie wine vault. As suspense builds, Montresor keeps asking if Fortunato would like to turn back because he seems ill. Fortunato continues to drink wine to ease his cough. Montresor gives several foreshadow clues to his intentions.
When they reach their destination, there is no Amontillado, but there is a hole in the wall. Montresor shackles Fortunato inside, and begins to seal up the wall with bricks.
As the last few bricks are laid, Fortunato screams for Montresor to stop, but it is too late. Montresor has enacted his revenge. Montresor enjoys hearing the torture of Fortunato. Then the screaming stops and all he hears are the jingling of the bells.
Montresor replaces the bones of the crypt. Montresor walks away knowing that Fortunato has met his fate. In the end, he claims that no one has disturbed them for 50 years; he has gotten away with his revenge.
