Academy Award nominee and Golden Globe winner Paul Giamatti stars as King John in this epic historical adventure detailing the siege of Rochester Castle in the year 1215. Forced under duress to sign the Magna Carta, an enraged King John assembles a rogue army and fights to take back England by force. As the king sets his sights on London, the only thing standing between him and total victory is Rochester, where the brave Baron Albany Brian Cox prepares to fight back until the cavalry arrives. Chief among Baron Albany's small yet determined rebel army is a Templar Knight James Purefoy still haunted by his reprehensible actions during the Crusades and wracked with love for Reginald de Cornhill's Derek Jacobi ravishing, neglected wife, Isabel Kate Mara. Later, as the king's army approaches, ruthless mercenary Beckett Jason Flemyng and young soldier Guy Aneurin Barnard vow to fight alongside Baron Albany to the death.
