A disease called the red death plagues the city and more than half of civilians are killed.
Instead of helping his people, Prince Prospero locks himself and friends into his castle far away
A few months later, Prince Prospero decorates his house beautifully with each room a different color. The seventh room, however was ominous so the dancers avoided it. Inside the room was a clock that rang every hour, further scaring the party-goers.
When the clock strikes midnight, a new guest appears which frightens the guests. Prospero is enraged and follows the new guest through all seven of his rooms with a knife, and catches up to it in the seventh.
The new guest turns around and the moment he does, Prospero drops dead on the floor.
The party goers then attempt to attack it but realize death cannot be contained and everyone dies.
