Don Rodrigo Díaz de Vivar, a fearless Castilian noble on his way to wedding vows with Doña Chimene, becomes the central figure around which a sweeping medieval drama unfolds. In this early act of the story, the 11th-century Moorish ruler Ben Yusuf of the Almoravid dynasty summons all the emirs of Al-Andalus to North Africa to rebuke their peaceable coexistence with Christian neighbors. His aim is clear: unite the Muslim world under one creed and one conquest, and he readies a formidable invasion to press his bid for domination. The emirs, meanwhile, return to Spain with orders to resume hostilities against the Christian kingdoms, setting a volatile stage for what is to come.
In the midst of impending conflict, the young Rodrigo chases a forbidden moment of personal joy. On the way to his wedding, he helps a threatened town resist an invading Moorish force. The act of mercy is a turning point: he frees two captured emirs, though this mercy could easily be read as reckless in a world where loyalty to king and faith weighs against personal honor. The captives, al-Mu'tamin of Zaragoza and al-Kadir of Valencia, pledge loyalty to Rodrigo after he insists they vow never to seize lands belonging to King Ferdinand of Castile again. The title El Cid—a Castilian honor meaning milord—begins to cling to him as the emirs acclaim his prowess and mercy.
In the halls of power, the mercy earns Rodrigo severe political trouble. He is accused of treason by Count Ordóñez, a charge backed by Chimene’s father, Count Gormaz, the king’s champion. Rodrigo’s aging father, Don Diego, challenges the accusation, and a brutal duel erupts when Gormaz strikes Don Diego. Rodrigo fights to defend his father’s honor and defeats Gormaz, ending the duel in a climactic moment that shakes Chimene’s loyalties. Witnessing Gormaz’s death, Chimene vows vengeance and withdraws her affection for Rodrigo, sealing a personal rift that will echo through the ensuing decades.
Seeking to prove himself, Rodrigo offers the king his service as champion and accepts the task of capturing a Moorish city. He wins Calahorra in single combat to the death and, in a fragile balance of mercy and power, asks that Chimene join him in marriage so they can secure a future for his growing family. Chimene promises Ordóñez she will marry him if he kills Rodrigo, a promise that triggers a dangerous game of trust and betrayal. When Ordóñez is captured by al-Mu'tamin, Rodrigo chooses mercy once more, forgiving the traitor and enabling his return. Rodrigo and Chimene marry, though the union remains unconsummated, as Rodrigo refuses to take Chimene while she does not give herself out of love. She withdraws from him and seeks sanctuary in a convent.
The crown then shifts with the death of King Ferdinand. His two sons, Alfonso and Sancho,-and their sister Urraca- face a fraught division of the realm, with Sancho demanding an undivided Castile and the other territories apportioned among the siblings. The brothers’ feud escalates into violence when Alfonso instigates a knife fight, and Sancho overpowers him. Rodrigo, loyal to the king’s line, but bound by oath to protect all of Ferdinand’s children, intervenes to bring Alfonso under his guard and to Calahorra, shaping a tense interlude in which Rodrigo cannot openly choose a side in the dynastic strife.
Ben Yusuf’s forces descend upon Valencia, the vital beachhead guarding Spain’s southern flank, and the invader hires a seasoned warrior, Dolfos, to strike at Sancho and inflame suspicions of Alfonso. Alfonso’s coronation becomes a watershed moment: El Cid secures his oath from Alfonso to clear his name of involvement in the alleged crime, but the king’s trust remains fractured. Chimene, realizing her enduring love for Rodrigo, joins him in exile, and the couple’s fortunes waver as they raise twin daughters in a life lived on the move and in the shadow of political intrigue.
Years pass, and the aging hero is recalled to defend Castile from Ben Yusuf’s looming armada. In a bid to blunt the Moorish siege, Rodrigo forms a pragmatic, if uneasy, alliance with the emirs and lays siege to Valencia. Al-Kadir, who betrayed his oath to Rodrigo, sides with the Moors, while Alfonso remains wary of a direct alliance with El Cid’s Muslim allies. The clash at Valencia culminates in a brutal morning when Omar’s forces press the city’s defenses and the defenders must decide how far they will go to endure.
A brutal sequence follows: Ordóñez is tortured and killed after a reconnaissance mission, and Rodrigo’s supporters rally to his cause as the siege continues. The people of Valencia suffer, yet Rodrigo finds a way to win their trust by hurling bread into the city via catapults, a symbolic gesture that wins the starving citizens over to his camp. In a turning point, the Moors’ morale falters as al-Mu'tamin and his army face a stubborn, unified defense. Despite the odds, El Cid refuses to claim the crown for himself, choosing instead to offer the crown to Alfonso.
Ben Yusuf arrives with an overwhelming invasion force, and Valencia becomes the last stand between the Moorish ambitions and a fractured Christian realm. Ordóñez’s fate underscores the peril, and the defenders rally behind Rodrigo, whose strategic genius and steadfast leadership sustain the resistance. In the climactic moment, Rodrigo is struck by an arrow and is carried back to the safety of the city, where doctors warn that removing the arrow could save his life but would leave him incapacitated for a long time. Refusing to abandon his army, he asks Chimene for a sacrifice: she must let him ride back into battle, even if it means death.
In his final hours, an anguished Alfonso visits Rodrigo’s bedside and seeks forgiveness, a moment that caps their long, painful entanglements. Rodrigo grants forgiveness, and Alfonso vows to protect Rodrigo’s children. Rodrigo dies, and a rumor of his death sweeps the land. The allies honor his final wish: with the help of an iron frame, his body is propped and strapped to the back of his horse, Babieca. Guided by both King Alfonso and Emir al-Mu'tamin, the mounted charge becomes a terrifying illusion for Ben Yusuf’s army, who fear the dead knight has risen. In the panic that ensues, Ben Yusuf is overthrown and crushed beneath Babieca’s hooves, and his army collapses. The battle ends with a collective prayer for the soul of the knight who brought unity and hope to a troubled realm. The film closes with El Cid’s horse riding along the coast, a lasting image of a warrior whose legend outlived his life.
> God to receive the soul of the purest knight of all.
