Mozart's sparkling comic opera of assumed identities and infidelity, Cosi fan tutte, begins with a bet as Don Alfonso sets out to prove that no woman can be faithful to her lover. Head over heels in a double romance with two sisters from Ferrara, the young soldiers Guglielmo and Ferrando put Fiordiligi and Dorabella to the test, pretending to go to war but returning, in exotic disguise, to seduce each other's fiancee. What starts as an innocent game turns into a cruel test as Dorabella and Fiordiligi's fidelity begins to waver. Aided and abetted by Despina, the sisters' maid, herself disguised as a doctor, Don Alfonso seems sure to win the bet. A wedding party is planned but who will end up with whom? In a sublime evening of al fresco serenades, vocal fireworks and volcanic emotions, anything could happen.
