The crown weighs heavily on King Henry IV. Relations are poor with the Welsh and the Scottish. His former allies from Northumberland, who helped him seize the throne, are revolting over an argument of succession. And his good-for-nothing son Prince Hal would rather spend his time drinking with lowlifes, like the fat, pompous, and charismatic Falstaff, than learning the ways of the court. As the revolution reaches a boiling point, the Prince must step up to his long-neglected responsibilities, make peace with his father, rally together an army of his drunken friends, and finally prove himself fit for the throne.
