The heir to the throne, Prince Hal (Tom Hiddleston), defies his father, King Henry (Jeremy Irons), by spending his time at Mistress Quickly's (Julie Walters) tavern in the company of the dissolute Falstaff and his companions. The King is threatened by a rebellion led by Hal's rival, Hotspur (Joe Armstrong), his father Northumberland (Alun Armstrong) and his uncle Worcester. In the face of this danger to the state, Prince Hal joins his father to defeat the rebels at the Battle of Shrewsbury and kill Hotspur in single combat.
