This drama is classified as a comedy play by William Shakespeare. However it is also referred to as a 'problem play', because it cannot be easily described as either a tragedy or comedy. The story of the plot centres on Angelo who has been empowered by the Duke of Vienna to rule his land, whilst he wanders about disguised as a friar to investigate the moral decay of his dukedom. Resorting to an old law against fornication to enforce his strict standards of morality, Angelo proceeds to condemn fornicators to death. One of these fornicators is Claudio , a young man who has had pre-marital sex with his fiancee. Claudio's sister Isabella pleads for her brother's life. Angelo's lust is aroused and he uses his power to blackmail Isabella into his bed. Fortunately the Duke overhears. Angelo ends up in the bed of Mariana , a woman from his undisclosed past. Claudio is allowed to live happily ever after with his fiancee, and the virtuous Isabella ends up the Duke of Vienna's bride
