Could you please check the following summary I tried to make shorter?

1) The Red Death has always killed many people. So Prince Prospero decides to shut himself with his friends in his castle.
2) Nobody can leave or enter it. It has rooms and windows of the same colour except for one that is black and red. One day Prospero’s friends are having a party.
3) They only stop when the pendulum is striking the hours. At midnight a strange man with a red costume and a death mask turns up and moves everybody.
4) Prince Prospero tries to stop him but he and his friends die. It was the Red Death.
5) If I hadn't missed the bus, I would have managed to arrive on time.
