Ironclad

In the year 1215, King John signs the Magna Carta under pressure from the barons, a document that grants freedom and rights to all Englishmen. However, the king soon goes back on his word and hires a mercenary army under the leadership of Tiberius to regain his power. A group of seven brave men, including three Templar knights, set out to resist the king's oppression and defend Rochester Castle, a strategic stronghold that controls southern England. The group faces a brutal battle against John's army, but their heroism and sacrifice will not be forgotten.
