In Messina, a messenger brings news that Don Pedro, a prince from Aragon, will return that night from a successful battle, Claudio being among his soldiers. Beatrice, Leonato's niece, asks the messenger about Benedick, Don Pedro's companion, and makes sarcastic remarks about his ineptitude as a soldier. Leonato explains that "There is a kind of merry war betwixt Signor Benedick and her." Upon the arrival of the soldiers, Leonato welcomes Don Pedro and invites him to stay for a month, Benedick and Beatrice resume their "merry war " and Pedro's illegitimate brother Don John is introduced. Claudio's feelings for Hero, Leonato's only daughter, are rekindled upon seeing her, and Claudio soon announces to Benedick his intention to court her. Benedick, who openly despises marriage, tries to dissuade his friend but Don Pedro encourages the marriage. Benedick swears that he will never get married. Don Pedro laughs at him and tells him that when he has found the right person he shall get married. A masquerade ball is planned in celebration of the end of the war, giving a disguised Don Pedro the opportunity to woo Hero on Claudio's behalf. Don John uses this situation to get revenge on his brother Don Pedro by telling young Claudio that Don Pedro is wooing Hero for himself. A furious Claudio confronts Don Pedro, but the misunderstanding is quickly resolved and Claudio wins Hero's hand in marriage.
