Riccardo, a follower of Cromwell and his Puritans, and Arturo, a staunch Cavalier who supports the Stuart cause, are both in love with Elvira, the daughter of Lord Walton. Walton had originally promised Riccardo his daughter’s hand in marriage but subsequently relented, not wishing to disregard the feelings of his daughter, who is in love with Arturo. The preparations for the nuptuals of Elvira and Arturo are in full swing.
Elvira as yet knows nothing of her good fortune. Her uncle, Giorgio, informs her that he has interceded on her behalf with his brother, her father, who has now agreed to her marrying Arturo.
Arturo arrives for the festivities. On discovering that a prisoner in the fortress under sentence of death is, in fact, Queen Enrichetta, the widow of Charles I of England, he enables her to escape by disguising her in Elvira's bridal veil. Elvira interprets this as desertion and loses her reason.
The English parliament has sentenced Arturo to death, and Elvira no longer sees any sense in her life.
Giorgio hopes that a sudden piece of good news will cure Elvira and restore her to reason, and what better news than that Aturo should be pardoned. Giorgio persuades Riccardo to spare Arturo, if the latter does not fight on the side of the Royalists in Cromwell's impending battle against the Cavalier followers of the Stuarts.
Arturo has returned to the fortress secretly to seek out Elvira and convince her of his continued devotion. Cromwell's soldiers apprehend him and threaten him with execution. At this very moment Elvira suddenly becomes aware of the situation and pleads, in vain, for Arturo's life. At the very last moment a messenger arrives with the news of Cromwell’s defeat of the Stuart followers. Cromwell has issued a pardon for all prisoners. Arturo is freed and there is now nothing to prevent the lovers from marrying.
