In a dramatic turn of events, the Duke of Vienna's sudden departure leaves the strict Angelo in charge, resulting in a devastating sentence for Claudio, who is condemned to death for having premarital sex. Isabella, a nun-in-training and Claudio's sister, is a skilled advocate who tries to intervene, but instead, Angelo proposes a shocking deal: Isabella must sleep with him to spare Claudio's life. Desperate for help, Isabella turns to a sympathetic priest, who is none other than the Duke in disguise, and together they concoct a plan to bring justice to the situation.
