In the Duke's absence from Vienna, his strict deputy Angelo revives an ancient law forbidding sex outside marriage. The young Claudio, whose fianc e is pregnant, is condemned to death by the law. His sister Isabella, soon to become a nun, pleads with Lord Angelo for her brother's life. But her purity so excites Angelo that he offers her a monstrous bargain - he will save Claudio if Isabella will visit him that night.
