Count Claudio falls in love with Hero, the daughter of his host. Hero’s cousin Beatrice (a confirmed spinster) and Benedict (an eternal bachelor) are each duped into believing the other is in love with them. Claudio is deceived by a malicious plot and denounces Hero as unchaste before they marry. She faints and is believed dead, but recovers to be proved innocent by a chance discovery. Benedict wins Beatrice’s love defending her cousin’s honour, and to his surprise, Claudio is reunited with Hero, who he believed dead.
