This is Illyria, folks! Our heroine is shipwrecked. Her brother presumably drowned. Disguising herself as a boy, she joins Duke Orsino's court and is sent as his emissary to the Countess Olivia, who's mourning the death of her brother. Olivia falls for the youth. Mistaken identity, gender confusion, a mordant clown, a pompous majordomo, whackadoodle relatives (Sir Toby) — a great deal of fun!
