Twelfth Night

Viola is shipwrecked on the shores of Illyria. She loses contact with her twin brother, Sebastian, whom she believes dead. Dressed as a eunuch and masquerading as a young page under the name Cesario, she enters the service of Duke Orsino. Orsino is in love with the bereaved Lady Olivia, whose brother has recently died, and decides to use "Cesario" as an intermediary. Olivia, believing Viola to be a man, falls in love with this handsome and eloquent messenger. Viola, in turn, has fallen in love with the Duke, who believes Viola is a man, and who regards her as his confidant. When Sebastian arrives on the scene, confusion ensues.
