Gabriella has been forced to marry Fayel after her childhood love Raoul is presumed to be dead. In fact, Raoul is not dead. He has saved the life of the King and has come to Fayel's castle ostensibly to be rewarded by the grateful King. However, his real purpose is to see Gabriella. She repulses his advances, but admits that she still loves him. Both are dealt a blow when the King offers the hand of Almeide, Fayel's sister, to Raoul as reward for his valor. Raoul pleads with Gabriella for her love one last time, but is caught by Fayel and the court. The King resolves that a duel will be fought. Gabriella is imprisoned, and Raoul is slain.
