Furtuna (The Tempest) is a play about King Alonso of Naples and his entourage who sail home for Italy after attending his daughter Claribel's wedding in Tunis, Africa. They encounter a violent storm, or Tempest. Everyone jumps overboard and are washed ashore on a strange island inhabited by the magician Prospero who has deliberately conjured up the storm. Prospero is in fact the rightful Duke of Milan who had been put to sea to die with his three-year-old daughter Miranda by his brother, Antonio who was in league with of King Alonso.

Prospero and Miranda live in a cave on the island which is also inhabited by Ariel, a sprite who carries out the bidding of Prospero, and the ugly, half human Caliban. Caliban deeply resents Prospero as he believes that he is the rightful ruler of the island. He plots with some of King Alonso's company to murder Prospero. Miranda and Ferdinand fall deeply in love. Ariel rebukes King Alonso for his previous plotting against Prospero. More plots against Prospero are developed but they fail thanks to his magic. The play ends with all offenders repenting, even Caliban. Prospero regains his dukedom, Ariel calms the Tempest and everyone, except Caliban, leaves the island.
