Synopsis.
The play is set in the court of Malfi (Amalfi), Italy. The young Duchess has recently been widowed, but her brothers, Ferdinand and the Cardinal, do not wish her to share their inheritance with a new spouse. They thus forbid her from remarrying. The brothers place Daniel de Bosola in her household as a spy. Nonetheless, the Countess falls in love with Antonio, her steward, and they secretly marry. Eventually, the brothers discover the marriage and imprison their sister. In the climatic duel, Bosola and Ferdinand wind up killing each other.
