In thirteenth-century England, a Knights Templar and a few of the Barons men fight to defend Rochester Castle against the tyrannical King John.

It is the year 1215 and the rebel barons of England have forced their despised King John to put his royal seal to the Magna Carta, a noble, seminal document that upheld the rights of free men. Yet within months of pledging himself to the great charter, the King reneged on his word and assembled a mercenary army on the south coast of England with the intention of bringing the barons and the country back under his tyrannical rule. Barring his way stood the mighty Rochester castle, a place that would become the symbol of the rebels' momentous struggle for justice and freedom.

King John Lackland reneges in 1215, the year the barons force him to sign to Magna Carta, on its parliamentary terms to resume his tyrannical misrule, and raised an army of pagan mercenaries to smash those barons who dare resist again. William d'Aubigny's warrior band, including knight Templar Thomas Marshal and his squire Guy, decides to make a stand in Rochester, a strategic castle to bar the road to London, so they force its Lord, Baron Reginald de Cornhill, to side with them after eliminating the Danish watchdogs. Captain Tiberius' mercenary band fails for months to make their numeric superiority count during a bloody siege, over which John presides personally, eager to take the castle before French and/or domestic rebel reinforcements may arrive. Baron Reginald's wife Isabel regrets their arranged marriage, enough to nearly openly lust for handsome crusade veteran Thomas, who, however, takes his order vows seriously.—KGF Vissers
