Separated from her twin brother Sebastian after a shipwreck, Viola disguises herself as a boy to serve the Duke of Illyria. Wooing a countess on his behalf, she is stunned to find herself the object of his beloved's affections. With the arrival of Viola's brother, and a trick played upon Malvolio, the countess's steward, confusion reigns in this romantic comedy of mistaken identity. The gentle melancholy and lyrical atmosphere of Twelfth Night, enlivened by a comic sub-plot of considerable accomplishment, have long made the play a favourite with Shakespearian audiences.
