Montresor is the narrator and is introduced to the readers. He claims that Fortunato has gravely insulted him, and is plotting to get his revenge. He is planning to seek great revenge, he exclaimed "I must not only punish but punish with impunity" (Poe 1). Although, the reader was not told what Fortunato has done or said, he emphasizes that it was unforgivable.
During a Carnival, Montresor encounters 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 to be ill. Montresor suggests that he will just go to Luchreci which makes Fortunato envious.
Montresor lures Fortunato down into the dark and eerie wine vault which is in the catacomb which is filled with skeletons all around. As suspense builds, Montresor keeps asking if Fortunato would like to turn back because he seems ill. But Fortunato denies and says to proceed on. The catacomb has nitre so Fortunato's cough gets more intense as they go through the catacomb.
When they reach the end, there is no Amontillado, but instead there is a hole in the wall. Montresor then shackles Fortunato inside, and begins to seal up the wall with bricks. "For the love of God, Montresor!" cries Fortunato for mercy (Poe 83). Montresor ignores the call for mercy and he continues sealing up the wall with bricks.
As Montresor lays the few last blocks, Fortunato screams for Montresor to stop, but it is too late. Montresor has enacted his revenge. As Montresor places the few last blocks, he starts to feel bad somewhat but denies and keeps going. Slowly the mercy call of Fortunato starts fading as the walls are sealed up.
Montresor seals the wall completely and walks away with only the sound of Fortunato’s jingling bells sounds roaming in the tomb. In the end, he claims that no one has disturbed them for 50 years; he has gotten away with his plot! He fully got revenge on the insults that were "unforgivable". The story comes to an end and Montresor says " In pace requiescat!"(Poe 89) which means "Rest In Peace".
