The Helmers are all set to enjoy Christmas. Torvald has been promoted and Nora is delighted. Everything at last seems to be going right, until a visitor arrives uninvited and causes them to question just how perfect is their marriage. Henrik Ibsen's "A Doll's House" caused outrage both in its style and subject matter when first staged in 1879. Zinnie Harris' retelling is played against the backdrop of British politics at the turn of the last century - to reveal a world where duty, power and hypocrisy rule. Zinnie Harris' version of "A Doll's House" premiered at the Donmar Theatre, London, in May 2009.
