While everyone else suffer from the disease know as the "Red Death", Prince Prospero was partying up in his Abbey with knights and other very wealthy people.
We will be safe in here from the "Red Death", we can party all night.
Now this is epic
As the party continues, an unknown intruder chases Prospero through seven colored rooms. It was nearly midnight. The intruder looked like the "Red Death". In the last room, Prospero tries to engage with the intruder.
The Intruder ended up killing the Prospero. The partiers figured Prospero died and tried to avenge him. All the guests ended up dying too.
