The play concerns twins who get separated during a storm at sea. Viola disguises herself as a man and this causes all sorts of problems for her and confusion for other characters. This confusion is increased when her lost brother Sebastian arrives on the island.
The confusion is only resolved when Viola and Sebastian meet up at the end of the play.
The comedy lies in the confusion that is created by various characters in the play.
In Twelfth Night the main characters are those who are important people in the play’s society (Duke Orsino and Countess Olivia and Viola) and we follow their attempts to fall in love.
The more minor characters are those who are lower down the social ladder but are still important in the play (Sir Toby Belch, Sir Andrew Aguecheek and Maria). Their actions also revolve around their attempts to fall in love
