In this scene, Fortunato insults Montresor at the carnival.
Montresor does not take the insult well. He lures Fortunato into the catacombs to get his revenge.
Montresor tricks Fortunato into becoming more drunk. He claims that the wine in the cellar will make him feel better and less whoozy.
When they reach their "destination" there is no Amontillado. There is only a hole in the wall. Montresor chains Fortunato to the walls and begins to block the hole with bricks.
As Montresor laid the last few blocks of stone, Fortunato screams for Montresor to stop. His screams are too late because Montresor has already completed his revenge.
Montresor walks away from his soon to be murder and only hears the sound of Fortunato's jingling jester bells. He replaces the bones in the crypt and claims that no one has disturbed them in over 50 years/. He got away with murder!
