During the 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, 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 is 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.
When they reach their destination, there is no Amontillado, 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, buts is too late. Montresor has enacted revenge.
Montresor walks away with only the sound of Fortunato's jingling jester bells echoing in the tomb. He replaces the bones of the crypt. In the end he claims that nobody has disturbed him for 50 years.
