Cid: Ximéná and Rodrigo love each other, but in order to remain worthy of each other, they decide to fulfill the command of honor. Don Rodrigo avenges the insult that Ximéná's father caused his father, and Ximéná asks the king to punish Rodrigo. The king forgives Rodrigo-Cid for killing Ximéná's father, Don Gómez, in the name of the honor of his family, because Rodrigo will save the land from the Moorish invasion.
