“Often seen as one of Shakespeare’s ‘problem plays’, the plot centres on Angelo, a puritan hardliner on a mission to clean up the city he is put in charge of, and the sister of a man he sentences to death, Isabella. After pleading for her brother, Angelo offers to save him in return for sex. … The role swap will probably take place about halfway through, with some scenes being replayed, including the key moment when Angelo makes the offer to Isabella.”
