Synopsis
At Messina, Don Pedro, an Italian prince from Aragon and his deputies, Claudio and Benedick have just returned from a successful military campaign. Leonato, the governor of Messina, welcomes them for passing by the city and invites them to stay for a month.
Benedick and Leonato's niece, Beatrice, longtime adversaries, carry on their "merry war of words". Claudio’s feelings for Hero, Leonato's young daughter, are kindled on his seeing her, and Claudio soon announces to Benedick his intention to court her. Benedick tries to dissuade his friend, but is unsuccessful in the face of Don Pedro’s encouragement. While Benedick teases Claudio, Benedick swears that he will never get married saying,
That a woman conceived me, I thank her; that she brought me up, I likewise give her most humble thanks: but that I will have a recheat winded in my forehead, or hang my bugle in an invisible baldrick, all women shall pardon me. Because I will not do them the wrong to mistrust any, I will do myself the right to trust none; and the fine is, for the which I may go the finer, I will live a bachelor. (Act 1 Scene 1)
To that Don Pedro says, "I shall see thee, ere I die, look pale with love," (Act 1 Scene 1). Later, Don Pedro says "Well, as time shall try: 'In time the savage bull/ doth bear the yoke," (Act 1 Scene 1). This exchange sets up the comical premise for the play.
A masquerade ball is planned in celebration, 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 and Claudio by telling young Claudio that Don Pedro is actually wooing Hero for himself. Claudio then becomes furious at Don Pedro and confronts him. The misunderstanding is quickly resolved and Claudio wins Hero's hand in marriage.
Don Pedro and his men, bored at the prospect of waiting a week for the matrimonial ceremony to take place, harbor a plan to matchmake Beatrice and Benedick. The men, led by Don Pedro, proclaim Beatrice’s love for Benedick while knowing he is eavesdropping on their conversation. The women, led by Hero, do the same likewise to Beatrice. Struck by the "revelations", Beatrice and Benedick, neither willing to bear the reputation of pride and scornfulness, each decide to requite the love of the other.
Meanwhile Don John, Don Pedro's bastard brother, is a malcontent who plots to ruin Claudio and Hero’s wedding plans by casting aspersions upon Hero’s character. His follower Borachio courts Margaret, Hero's chambermaid, calling her “Hero”, at Hero’s open bedroom window while Don John leads Don Pedro and Claudio to spy below. The latter two, mistaking Margaret for Hero, are convinced by what is evidence of Hero's infidelity.
The next day, during the wedding at the church, Claudio climactically refuses to marry Hero. He and Don Pedro humiliate Hero publicly before a stunned congregation. The two leave brusquely, leaving the rest in shock.
Hero, who has fainted from shock, revives after Don Pedro and Claudio leave, only to be reprimanded by her father. The presiding Friar interrupts, believing Hero to be innocent, and he convinces the family to feign Hero's death in order to extract the truth and Claudio’s remorse.
Leonato and Antonio, Hero's uncle, subsequently blame Don Pedro and Claudio for Hero’s death, and both challenge Claudio to duels. Benedick, forcefully prompted by Beatrice, does the same.
Unbeknownst to everyone, however, on the night of Don John's treachery, the local Watch has apprehended Borachio and his ally Conrade. Despite the Watch's comic ineptness (headed by constable Dogberry, a master of malapropisms), they have overheard the duo discussing their evil plans. The Watch arrest them and eventually obtain the villains' confession, whilst informing Leonato of Hero's innocence. Though Don John has meanwhile fled the city, a force is sent to capture him. Claudio, though maintaining he made an honest mistake, is repentant; he agrees to not only post a proper epitaph for Hero, but to marry a substitute, Hero's cousin, in her place.
During Claudio’s second wedding, however, as the dancers enter, the "cousin" is unmasked as Hero herself, to a most surprised and gratified Claudio. An impromptu dance is announced. Beatrice and Benedick, prompted by their friends’ interference, finally confess their love for each other. As the play draws to a merry close, a messenger arrives with news of Don John’s capture – but his punishment is postponed another day so that the couples can enjoy their newfound happiness.
