Ruy Díaz de Vivar is a Young page who loyally serves his master, Sancho, the future King of León and Castile. While he fights to come out on top in the Court thanks to his natural talent with a sword, he gets caught up in a conspiracy to overthrow the King, which would cause as much bloodshed, pain, and death in the Christian Kingdoms as it would in the Muslim taifas.
