King Richard (Ben Whishaw) is called upon to settle a dispute between his cousin Henry Bolingbroke (Rory Kinnear) and Thomas Mowbray (James Purefoy). Richard calls for a duel, but then halts it just before swords clash. Both men are banished from the realm. Richard visits John of Gaunt (Patrick Stewart), Bolingbroke’s father, who, in the throes of death, reprimands the king. After seizing Gaunt’s money and lands, Richard leaves for wars against the rebels in Ireland. Bolingbroke returns to claim his inheritance. Supported by his allies, Northumberland (David Morrissey) and the Duke of York (David Suchet), Bolingbroke takes Richard prisoner and lays claim to the throne.
