Summary

Twelfth Night is a story of love and confused identity. At the beginning of the play, after having survived a shipwreck, Viola (the play's protagonist) finds herself stranded in Illyria. She disguises herself as Cesario, a young man, and enters into the service of Duke Orsino.

Orsino is in love with the countess Olivia, but she does not return his affections. In order to woo Olivia, Orsino sends Cesario (who is actually Viola) to serve as his representative, but Olivia falls in love with Cesario instead. Meanwhile, Viola, in her service to Orsino, is drawn into close friendship with him and finds herself falling in love. Thus, the story of Twelfth Night revolves around this love triangle fueled by mistaken identities, by which Viola is in love with Orsino, who is in love with Olivia, who is in love with Cesario (who is actually Viola).

Viola's twin brother, Sebastian, is also traveling to Illyria with his friend Antonio. When they reach their destination, they separate. There is an additional subplot within Olivia's own household involving her uncle, Sir Toby Belch; her servant, Maria; her steward, Malvolio; and another would-be suitor to Olivia, Andrew Aguecheek. Entertaining themselves at the steward's expense, Maria leaves letters forged in Olivia's handwriting that lead Malvolio to assume that Olivia is in fact in love with him. Maria also advises him to present himself in such a manner that Olivia would find offensive. Malvolio finds these letters and falls for the deception.

Meanwhile, Olivia continues to be in love with Cesario, and Andrew notices her favor for Orsino's servant. Toby tries to push Andrew into fighting Cesario as a way to win Olivia's affections. However, Antonio stumbles upon the scene. Mistaking Viola for her twin brother, he comes to her defense, only to be arrested. Antonio looks toward the man he believes to be Sebastian for support—only to find, of course, that he does not know Antonio or anything about him....
