Much Ado About Nothing by William Shakespeare - This Shakespeare comedy follows the romances of two very different couples and the machinations of their friends that help and hurt their causes.
In Act I we meet all the main characters and are introduced to the conflicts. Sharp-tongued Beatrice and her cousin Hero are the two ladies, and Benedick and Claudio are the young men they are paired with. Beatrice and Benedick seem to have a past, indicated by her sarcastic jabs at him and his vehement declaration that he will remain a bachelor. Hero and Claudio, however, fall in love at first sight with barely a word spoken. We also meet Hero's father Leonato and Don Pedro, the prince. Benedick and Claudio are officers serving under Don Pedro in the war.
Later we meet Don John, Don Pedro's brother, and the villain of the piece. Don John is jealous of Claudio's rising fortunes and feels that his own position has been usurped by the younger man. Determined to remove his rival, Don John enters into a scheme with a couple of servants to trick Claudio into believing that Hero is unfaithful to him. Claudio falls for the deception, and accuses the innocent Hero during their wedding. Hero faints and Claudio storms out. More trickery is involved as Claudio is led to believe that Hero has died.
Meanwhile, there is an effort of matchmaking between Beatrice and Benedick, and despite their failed past romance, they do rekindle their affections, and after trading barbs and then witnessing the tragedy between Hero and Claudio, they declare their love for each other.
In the end, all comes right for Hero and Claudio as well. The scandal dies down a bit, Claudio grieves his lost love, and he finds out that it was a trick! Then Claudio agrees to an arranged marriage with a "niece" of Leonato's, and at the masked wedding, it turns out his bride is none other than Hero, who of course had not died after all.
