"Twelfth Night" by William Shakespeare is a romantic comedy written around 1601–1602. When twins Viola and Sebastian are separated by shipwreck, Viola disguises herself as a young man and enters the service of Duke Orsino. A tangled love triangle emerges as Viola loves Orsino, Orsino pursues the mourning Countess Olivia, and Olivia falls for Viola's male disguise. Meanwhile, a comic subplot involves elaborate revenge against Olivia's pompous steward, Malvolio, through pranks and deception that spiral hilariously out of control.
