Romeo, heir of the lordly Montague family of the Italian city of Verona, goes wearing a mask to a dance held by the Capulets, their bitter rivals in the city. There, Romeo falls head over heels for Juliet Capulet, and they are secretly married by the obliging Friar Lawrence. Following a fight, Romeo is banished from the city, and Juliet's father promises her in marriage to another young fellow, Paris. Juliet unwisely agrees to a plan suggested by Friar Lawrence, takes a drug which will make her seem dead for two days and is put into the family vault, expecting Romeo to collect her when she wakes up. However, Romeo fails to get Friar Lawrence's message, believes Juliet is dead, kills Paris, then drinks poison and dies by Juliet's side. On waking up, she finds Romeo's body and stabs herself to death. As a result (if a rather unlikely one) the Montague and Capulet lords make up their ancient quarrel and a new friendship blossoms between the warring factions.

Bolingbroke wrongly accuses Mowbray of killing Gloucester, the uncle of King Richard II. Richard (who in fact arranged the murder) orders a trial by combat between Bolingbroke and Mowbray, then turns this into exile for both of them. Bolingbroke's father, John of Gaunt, dies and Richard seizes his estates to pay for a campaign in Ireland. While Richard is off fighting the Irish, leaving the Duke of York as Regent, Bolingbroke invades England and the country rises in support of him. York vacillates, Richard lands in Wales, is arrested, and surrenders the crown to Bolingbroke, who becomes King Henry IV. A plot against Henry is discovered, Henry pardons his cousin Aumerle, but Richard is murdered while imprisoned at Pontefract.
