A lavish ball at the Capulet home. Disguised by masks, Romeo, Mercutio and Benvolio slip unannounced into the ball. When Romeo sees Juliet, he is immediately lovestruck. Taking advantage of the fact that Tybalt takes Paris away from Juliet, Romeo approaches her. He does not hide his delight and admiration. Romeo’s accidentally dropped mask reveals his face to Juliet’s gaze. But Romeo is recognized by Tybalt and, fearing possible complications, hurries to leave the house. Juliet is still under the impression of meeting Romeo. Who is this beautiful young man? Moonlit night. Romeo appears.

They confess their love to each other and swear loyalty. The square of Verona is noisy and fun. Juliet’s nurse sends a note to Romeo on behalf of her young mistress.

Laurence promises his help, hoping this marriage will reconcile the warring families of Montague and Capulet. Juliet appears. Lorenzo performs the wedding ceremony. Mercutio, Benvolio and their friends are having fun. Appearing on the bridge, Tybalt notices his enemies and, drawing his sword, rushes to Mercutio.

Romeo tries to separate them, but Tybalt, seizing the moment, strikes Mercutio a fatal blow from under Romeo’s arm. The death of a friend enrages Romeo. Drawing his sword, he challenges Tybalt to a duel and kills him. The family of the murdered man, gathered at his body, swears eternal vengeance on the family of Montague.

Romeo must say goodbye to Juliet. He is banished from Verona. The morning sun breaks into the room. The nurse tries in vain to comfort Juliet. Parents appear. Paris is with them. Juliet learns about her wedding, listens to the groom’s confessions, but resolutely refuses to submit to the will of her parents. After Paris leaves, a hail of reproaches falls on her. The will of the Capulet is adamant. Juliet is desperate. She decides to consult with Friar Laurence. Amazed by the girl’s boundless love for Romeo, the father gives her a potion: after drinking it, Juliet will fall into a dream, everyone will think that she is dead, and her body will be carried in an open – according to custom – coffin to the ancient crypt of the Capulet. Meanwhile Friar Laurence will notify Romeo, who is hiding in Mantua. The young man will immediately return to Verona, find Juliet awake and take with him to Mantua, where they will have unclouded days of happiness.

They hold out their hands in silence…The long-standing feud between Montague and Capulet is ended at the cost of the lives of two lovers…
