The magician Prospero tosses and turns in his sleep while a violent storm tosses a ship on the ocean. Prospero awakens with a start as lightning strikes the ship, and summons his servant, the spirit Ariel. Ariel tells Prospero the details of the storm, which was an illusion he created at Prospero’s command to lead the King of Naples (Alonso) and his crew to the island and trap them there.
