Twins Sebastian and Viola are shipwrecked on the coast of Illyria and are separated, thinking that each other are dead. Viola then disguises herself as a man and makes her way to the court of Orsino, a duke who is madly in love with the Countess Olivia. He sends Viola to woo Olivia and behalf of him, but Olivia falls in love with her, and she falls in love with Orsino. Alongside this plot, Sir Toby Belch and Maria, in love with each other, play pranks on Olivia's 'steward' Malvolio, by pretending that Olivia is in love with Malvolio. In the end Sebastian comes to the court of Orsino, Viola reveals her true identity, Sebastian and Olivia fall in Love, and so do Orsino and Viola.
