Twelfth Night, or What You Will, is a Shakespearean comedy about mistaken identity, love triangles, and disguise set in the land of Illyria. After a shipwreck, Viola disguises herself as a man named Cesario to serve Duke Orsino, but ends up in a love triangle with him and the Countess Olivia, who falls for Cesario (Viola). The plot thickens with the arrival of Viola's twin brother, Sebastian, leading to further confusion, a subplot involving the foolish Malvolio, and a chaotic resolution where everyone finds their match.
