In Normandy, in the year 1413, times are troubled. Sir Eustace de Villeroy prefers not to take sides in the conflict between England and France, but his castle is strategic. As a sign of loyalty, the French king compels him to send his wife, Dame Margaret, and her children to Paris as hostages. Guy Aylmer, a pageboy, goes with her as a counselor and bodyguard. Paris is turbulent, and soon the butchers' guild, adopting white hoods as their uniform, seizes the city, and besieges the house where Guy and his companions are staying. There is fighting, death, an escape, and eventually our hero Guy ends up in the thick of battle at Agincourt with King Henry V.
