It is set on a remote island, where the sorcerer Prospero, rightful Duke of Milan, plots to restore his daughter Miranda to her rightful place using illusion and skilful manipulation. He conjures up a storm, the eponymous tempest, to cause his usurping brother Antonio and the complicit King Alonso of Naples to believe they are shipwrecked and marooned on the island. There, his machinations bring about the revelation of Antonio's lowly nature, the redemption of the King, and the marriage of Miranda to Alonso's son, Ferdinand.
