Romeo is the son of Lord Montague, who has been engaged in a long-running family feud with Lord Capulet. Romeo, in disguise, sneaks into a ball given by Lord Capulet. He sees Juliet, the beautiful young daughter of Lord Capulet, and immediately falls in love with her on first sight. Romeo then goes to the Capulet house and stands in the garden beneath Juliet's window and has a long talk with her in which they pledge their love to one another. 

Romeo goes to Friar Laurence and arranges to be wed secretly to Juliet. Romeo is challenged to a duel by Tybalt, Juliet's cousin. He initially refuses to fight him, but when Tybalt kills Mercutio, Romeo's friend, Romeo then fights with and kills Tybalt. 

On hearing that Juliet is dead (which is actually not the case), Romeo buys poison in order to commit suicide. He goes to Juliet's tomb where he meets and kills Paris. He then drinks the poison and dies.
