Montresor and Fortunato enter the Catacombs with torches. Montresor offers Fortunato more wine to get him even more intoxicated, but does not make his plan obvious.
Fortunato in now passed out and Montresor chains him to the wall in a dark room. Montresor begins to lay bricks in the doorway in front of Fortunato. Fortunato wakes up while Montresor is laying the final brick, leaving Fortunato screaming.
Montresor gets done laying the bricks, and Fortunato stops screaming. Fortunato remains undisturbed until the next 50 years.
