Twelfth Night
Shipwrecked in Illyria and believing her twin brother Sebastian drowned, Viola disguises herself as a young man named Cesario and enters the service of Duke Orsino, who sends her to woo the mourning Countess Olivia on his behalf. Olivia promptly falls in love with Cesario instead, while Viola falls in love with Orsino, creating a tangle of misdirected desire that only the surprise arrival of the living Sebastian can resolve. A parallel comic plot sees the pompous steward Malvolio tricked by a forged love letter into humiliating himself before Olivia, for which he is imprisoned as a madman before the deception is finally exposed.
