Twelfth Night
A shipwrecked Viola, believing her twin brother dead, disguises herself as a boy named Cesario. She goes into service with Duke Orsino, whom she secretly comes to love. He sends her to woo Olivia, who falls in love with "him". Part of the mischief of the comedy is around this triangle of lovers.
The play also features Olivia's household: Sir Toby Belch, his drinking companion Sir Andrew, Olivia's maid Maria, her fool Feste, and her head of house, Malvolio, whom the others bully and abuse. When Viola's twin brother Sebastian arrives he is mistaken for Viola, but in the end will marry Olivia and Viola will marry the Duke.
