Operette is a musical in two acts composed, written and produced by Noël Coward. The show is a period piece, set in the year 1906 at the fictional "Jubilee" theatre. The story concerns an ageing Viennese operetta star, who warns the young ingenue not to marry a nobleman.
Cast in an Edwardian musical comedy, The Model Maid, Liesl Haren, a fading Viennese operetta star, has one more chance at stardom. Young Rozanne Grey, a member of the sextet of The Model Maid, falls in love with Nigel Vaynham, a nobleman serving in the army. Liesl counsels the younger woman not to marry him. Rozanne gains the leading role and stardom, but Nigel returns to the army, realising that a marriage to an actress would destroy his social reputation.
