Montresor is at a carnival and sees Fortunato. They began to talk,then Montresor offers to share a bottle of wine called Amontillado. However, this bottle was located in Montresor's catacombs. But Fortunato seemed very sick.
Montresor thought this was the perfect time to get his revenge on Fortunato because he felt like he had insulted him.
Fortunato fallows Montresor into his wine vault. Montresor pretends to act concern when Fortunato keeps coughing like crazy by asking if he would like to turn back and maybe do it some other time. But Fortunato says that he is fine, he drinks more wine to cool down his coughing.
When Montresor and Fortunato get to where they wanted to be, Fortunato realizes there is no wine. All he found was a whole in the wall. Montresor shackles up Fortunato into the whole and starts to build the wall with his bricks.
Before Montresor puts the last pieces of bricks up, Fortunato screams so Montresor screams even louder. That's when everyone knew Montresor had gotten the revenge he wanted.
Montresor walks away and all he could hear was the echo of Fortunato's jester bells ringing. Montresor says that no one has bothered them for half a century.
