One of Ibsen's best known plays, A Dolls House caused a sensation when first published, as it provided a critique on the conventions of Victorian marriage. Nora Helmer feels suffocated and belittled in her marriage to banker Torvald. When faced with blackmail as a result of an attempt to save her husband's life, Nora decides that the only way to discover the real world is to step outside the illusions within her doll's house.
