Fortunato and Montresor are talking about the amontillado and how Montresor has some in his basement but Forunato is way to sick to go to the damp basement.
They both walk down into the damp basement. As they walk down the stairs to the basement they talk about the amount of knowledge they both have about different types of wines.
"Amontillado! Amontillado! Amontillado!"
Once they get down the stairs Fortunato is very drunk so Montresorchains him up to the ground. Fortunato doesn't even realize he was tried up.
Fortunado realized what was going on. He was laying on the ground chained up because Montresor was trying to kill him.
Fortunado started to yell as a cry for help but it was already to late he would be locked in the basement forever. Montres or started to talk to him and as soon as he finished and waited for a response from him he died.
After Fortunado died, Montresor went upstairs and pretended as if nothing had happened.
