Henry IV finds himself facing uprisings from the Welsh chieftain Owen Glendower and impetuous young Harry Hotspur, son of the Duke of Northumberland, angry with the king for not paying Glendower ransom for his brother-in-law Mortimer. Another trial for Henry is the fact that his son, Prince Hal, keeps company with the older, reprobate drunkard Sir John Falstaff. Although the prince is his friend he is not above playing cruel jests on Falstaff, robbing him in disguise and returning his money after Falstaff has given an exaggerated account of his bravery in the hold-up. However Hal joins his father at the wintry battle of Shrewsbury to put down Hotspur's revolt, where Hal kills Hotspur in single combat - Falstaff later claiming credit for the deed. Hotspur is routed but Henry and Hal still have to face the uprisings of Glendower and Nortumberland, now joined by the archbishop of York.
