A deadly plague known as The Red Death which causes its victims to die a quick and gruesome death strikes the country.
While the disease spreads quickly across the country, Prince Prospero feels hopeful in his plan to lock up the palace to fend off The Red Death.
A few months after the castle was boarded up, the prince decides to throw a magnificent masquerade ball when the party goers soon become aware of an uninvited guest among them.
Prospero, after following the masked figure through all 6 rooms, he finally reaches the man and as soon as he confronts the figure, he dies.
Just after midnight, when the other guests reach the room, they begin attacking the figure. To their surprise, they find that there is no one underneath the mask and all of the guests die.
"And now was acknowledged the presence of the Red Death. He had come like a thief in the night. And one by one dropped the revellers in the blood-bedewed halls of their revel, and died each in the despairing posture of his fall."
