Twelfth Night (1601)
After her shipwreck, Viola – disguised as Cesario – agrees to speak for Orsino to Olivia, with whom he’s in love. But Olivia’s in mourning, and not interested. Until she meets Cesario.
Meanwhile Olivia’s “guests” convince her pompous servant Malvolio that she is in love with him. Now he’s a changed man.
But Cesario is suddenly being confused for someone else. Meanwhile Sebastian has appeared, and is inexplicably invited to marry Olivia.
Confusion reigns: Olivia is angry with Cesario for denying they’re married. Orsino is angry at the “betrayal”. Finally, Sebastian appears, the confusion is cleared up – and Orsino can marry Viola.
