Shakespeare's The Tempest takes place on a magical island. The story opens as a horrific storm causes a ship to crash stranding its men upon the shore of the island. As the weather clears, we learn that Prospero, guardian and ruler of the island, is the one who caused the storm (or tempest) in order to bring his brother Alphonso and his brother's men to the island. Having had past conflict between them, it is time for Prospero's revenge.
The next scene tells the story of Prospero and his daughter Miranda and how they came to the island 12 years before. With the help of Ariel, Prospero's magical chief agent and servant, the men from the ship were all brought to shore safely but split up into smaller groups throughout the island.
We learn that Ariel has been promised to be released from Prospero's hold if he completes these tasks without complaint. Then enters Caliban, chained to one place where he works for Prospero hauling wood and doing chores all day long. Caliban is the son of the witch Sycorax who locked up Ariel. When Prospero came to the island after Sycorax died, he freed Ariel to become his servant and took over Sycorax's son, Caliban, to be his servant.
Over the rest of the play, scenes play out leading to the confrontation between Prospero and his brother at the end. Prospero decides to let everyone free from his reign and makes amends with his family. Prospero gives his apology to all through the Epilogue and asks the audience to show their forgiveness by applauding.
