In the 12th century during the Crusader invasions, Saladin, raised with a commitment to justice and the freedom of Jerusalem, leads the Serhad Ghazis against the Knights Templar besieging Ascalan, a key city for Jerusalem's defense. Despite the state council's refusal, Saladin defies orders to aid Ascalan, facing both external enemies and internal conflicts. Amidst the chaos, a love blossoms between Saladin and Süreyya, the daughter of Ascalan's Emir. As they navigate their forbidden romance and the challenges of war, the question remains:

Turanşah's wrong decision changed the course of the war and brought Şehinşah to the brink of death. While the events in Asqalan caused chaos in the Zengi State, the security of the Pilgrimage Route was also endangered. While this incident causes Selahaddin to be tried in the court, it also progresses towards revealing the big secret. The people of Ascalan will blame Saladin for the loss they suffered and call the Zengis to account. Saladin will struggle under the pressure of the members of the council on the one hand and the people of Ascalan on the other. He now has to act more strategically as he continues his fight against the Crusaders. But Saladin was in big trouble with the state court before the Crusaders. Because he went to Askalan despite the negative decision of the court. He will now be tried for violating the court decision.

Saladin gained a powerful trump card in his fight against the Crusaders and captured Victoria and the Grand Master. However, during the exchange he plans to make for Askalan, an unexpected event occurs and the security of the Pilgrimage Road is endangered. This incident, which puts Saladin in a very difficult situation, causes him to face reactions from both Sultan Nureddin and Süreyya. On the other hand, the fact that Gabriel is aware of Saladin's moves indicates that there is a traitor in the palace. In the midst of all these crises, Saladin will need to both keep the captives and reveal the traitor inside. He takes action and puts forward a risky plan to achieve these goals. But the real betrayal will come from a place he never expected, and as a result, Sultan Nureddin will be assassinated.

Süreyya's unexpected betrayal both ambushed Saladin and caused the captives to escape. Sultan Nureddin was also seriously injured and underwent surgery, leaving him in a life-and-death struggle. While Nusreddin, who shot the Sultan, put all the blame on Turanşah, who was wanted as a traitor; He holds Saladin responsible for what happened. Not only does he lock Seahaddin and his companions in a dungeon to prevent the captives from chasing him, he also declares himself the regent of the throne. The state is now under his rule. From now on, he will withdraw from Ascalan and give up the issue of captives

Gabriel, who conquered Ascalan and caused great suffering to Muslims, died in a duel with Saladin. Nureddin, who came back to life, is very angry. He takes action to punish those who caused this and accuses Nusreddin of being a traitor and decides to execute him. As Victoria continues to escape, Saladin must catch them before the Crusaders. But Victoria falls into the hands of an unexpected person and all balances are turned upside down. On the other hand, another difficult obstacle awaits Saladin: A wild warrior named Gregor has sworn to avenge his older brother Gabriel. In response to the atrocities committed by Gregor, Sultan Nureddin and Saladin decide to besiege Askalan. But this will not be easy.

Nusreddin came to the palace unexpectedly and told Sultan Nureddin that he had learned that Saladin was not his real son. Saladin saved the captives from Gregor. Now it is time to conquer Ascalan with the participation of Sultan Nureddin. But Sultan Nureddin, whom Nusreddin threatens to reveal the secret, cannot go to the siege. This situation causes a harsh conflict on the front of Saladin and Sultan Nureddin. Gregor, who is fully vengeful towards Saladin, takes action immediately and kills the Alps and Halil that Saladin had rescued from captivity in a brutal move. Halil's death was met with great pain and anger in the Askalan tribe. In response to Gregor's action, Saladin virtually declares war. Nureddin is clear in his decision. He will not act without establishing unity with Muslim Gentlemen. Father and son come to a serious crossroads at this point, and Saladin sets out to fight alone.

Saladin and his companions engaged in a bloody war with Gregor and his strongest men. Saladin is about to defeat Gregor and take Ascalan, but the assassination of the Turkmen lords in the palace turns everything upside down. The tribes, who were summoned to form unity against the Crusaders, now drew their swords for revenge and stood against Sultan Nureddin. Faced with this great danger, Saladin begins to search for those responsible for the assassination that took place in the palace. A very secret and dangerous organization that has been sleeping for a long time has awakened again under the leadership of the Lord of the Mountain, and intends to end the peace among Muslims forever with the assassinations they carry out by hiding in the shadows! Saladin rolls up his sleeves to find the traitors who have infiltrated the deepest parts of the palace and the camps, on a path full of traps at every step, and reach the Lord of the Mountain.

Falling into the trap set by the Lord of the Mountain, Saladin was caught by Nusreddin with Izzeddin's corpse. While Sultan Nureddin was fighting sword with Böriler, he unexpectedly appeared as the Lord of the Mountain "Rashidüddin Sinan". While Selahaddin is arrested and taken to the palace to be tried, he escapes from Nusreddin's hands and goes after Reyhani to foil the game set on the state through him. He will not return without revealing the truth at all costs. Sultan Nureddin knows that Böriler will not be stopped any longer. In order not to shed brother's blood, he makes a decision that shocks everyone and takes İsmet Hatun as a prisoner and takes her to the palace. This move of Sultan Nureddin for unity will confuse the whole palace, especially Melike Hatun.

Selahaddin, with the aid of Reyhani's capture and execution for being an Assassin, learns the truth from Sultan Nureddin: he is not Nureddin's son, but rather Ayyub's. This revelation shatters Saladin, leading him to sever ties with Nureddin and his supposed family, feeling betrayed by the lies he's lived. Determined to pursue the Jerusalem cause alone, Saladin embarks on a new path. Meanwhile, Nusreddin, disillusioned after losing his secret, joins forces with Gregor and Victoria under Sinan's guidance, rebelling against Sultan Nureddin. Nusreddin declares himself sultan in Ascalan, dividing the Zengian state, and inciting tribes like Karategin to revolt against Nureddin, leaving the state in unprecedented peril.

Saladin falls into Gabriel's trap and sustains mortal wounds from Gabriel and Gregor. Sultan Nureddin quashes the threat of state division by eliminating his rebellious brother, Nusreddin. Believing there are no obstacles to his march on Ascalan, Sultan Nureddin postpones the conquest upon learning of Saladin's demise. Upon arriving at Saladin's headquarters, he is shocked to find Saladin dead, plunging both him and the Ayyubid family into profound grief. While Damascus mourns its hero, the Crusaders celebrate victory. Sultan Nureddin vows to avenge Saladin's death by conquering Ascalan. However, Eyyub's unexpected arrival sows doubt in their minds, raising the possibility that Saladin may still be alive and mobilizing everyone.

An unexpected miracle happened and Saladin, whom Karategin saved, was found safe and sound. Gabriel, who wanted to complete the job he left unfinished and kill Selahaddin, was caught by Selahaddin's comrades and his older brother Turanşah. Now Saladin will revolt and the conquest of Ascalan will take place. Gabriel will get what he deserves and will answer for what he did to Saladin. However, suddenly the Lord of the Mountain appears and saves Gabriel from the circle of death he fell into. Even though Saladin is dying to conquer Ascalan, there is only one thing on his mind... Süreyya... Süreyya is in captivity in the hands of his enemies in Ascalan. Moreover, they use him as a trump card to prevent the siege of Askalan. While Sultan Nureddin, who wants to put an end to blasphemy, is preparing his army for a siege, on the other hand, Saladin will race against time and throw himself into danger to save Süreyya from the clutches of death.

Saladin and Süreyya are entrusted with the administration of Ascalan by Sultan Nureddin, marking the beginning of new conquests for the Zengis under Saladin's leadership as "Emir Saladin." However, Gaza faces an unexpected disaster as Abram, a wealthy Jewish figure, leads a massive Crusader army to massacre Muslims. Selahaddin anticipates the impending massacre and acts to protect the people of Gaza, but Melik Mevdud, known as the "Tiger of Mosul," disrupts Selahaddin and Nureddin's plans by arriving in Ascalan.

Saladin, captured while trying to save his people, remains silent under torture, determined to protect his secrets. Avram seeks these secrets to neutralize the Zengi State and establish his own kingdom, while Gregor threatens to destroy Saladin's tribe if he doesn't comply. Sultan Nureddin faces a dilemma: save Saladin and risk his tribe, or let Saladin perish to preserve the state. Meanwhile, Mevdud manipulates events to thwart Saladin's tribe and continues his schemes through Karategin. The Ayyubids defend their camp against Mevdud and prepare for potential Crusader attacks, risking everything to safeguard their people and legacy.

Avram and Gregor conspire against Saladin, but Saladin escapes with the help of allies. Gregor considers a peace treaty proposed by Melik Mevdud, which would abolish Saladin's tribe, but Saladin interrupts negotiations. Sultan Nureddin warns Saladin against endangering the tribe or his state.

Abram caused Saladin to fall into the death trap he set, and Gregor surrounded Saladin's camp and took action to massacre the people in the camp. While Avram thinks he has captured Saladin, Saladin and his men stand up and start fighting, and he escapes from this battle with the help of the Secrets. Gregor, who took action to attack the Oba, is confronted by the Zengi army while he was about to attack the Oba. Moreover, Melik Mevdud is the leader of the army. Melik Mevdud offers an offer to Gregor, who resists raiding the camp.

Gregor raided Saladin's camp and took the entire tribe into captivity. Learning this, Selahaddin took action to save his tribe, but Melik Mevdud appeared before him and Selahaddin and Melik Mevdud came to blows. Sultan Nureddin was caught in the middle of the assassins. Selahaddin asks Melik Mevdud to get out of his way for the sake of his tribe. His only concern is to get the chest and solve all the issues before Sultan Nureddin comes. Realizing that Melik Mevdud will not retreat, Selahaddin escapes from Mevdud's grasp with one last move. Now he is both a fugitive from the state and his tribe is under great captivity and oppression.

aladin took action to save his tribe, which was occupied by Gregor, and managed to infiltrate the tribe by pretending to be captured. Avram, who met with Mevdud to take back the ark of the covenant, was cornered by Mevdud. Confronted with Saladin, Gregor escapes from the camp with a heavy defeat. Mevdud not only spoils Avram's game, but also confiscates the gold and releases Avram. While Saladin, who saved his tribe, was about to start preparations for the conquest of Gaza, he was once again shocked by a decision made by Mawdud. Mevdud, who cannot stomach the increasing rise of Selahaddin, appoints Karategin as the head of Selahaddin's tribe. While Selahaddin never accepts this situation, tensions arise between Karategin and Selahaddin, who come face to face again.

Despite his serious wounds, Saladin jumps into the river after Sultan Nureddin. The news that Sultan Nureddin fell into the river with a serious wound created a bombshell effect in the palace. Meanwhile, Mevdud takes action and searches are carried out in the place where Nureddin disappeared. Although Saladin managed to get out of the river he fell into, he was seriously injured. Despite everything, he sets out to search for Nureddin.

Saladin and Sultan Nureddin, who are in the middle of a large crusader army, resist them fearlessly, with the arrival of Ömer Mella, all the cards pass to Saladin. While Ömer Mella and Selahaddin's plan saves them from this circle of death, Victoria goes crazy. She has lost once again. Mevdud, who took control in Nureddin's absence and declared his sultanate, passes judgment on Shirkuh and Isfahani, especially Melike Hatun, who opposed him. Melike will be exiled from the palace, and Shirkuh and Isfahani will be executed. Sultan Nureddin's return to the palace at the moment of execution creates a shock effect. Sultan Nureddin very harshly demands an accounting from Mevdud and Melike, who caused chaos in his absence and put the state in a difficult situation.

Saladin killed Gregor and turned towards Gaza, causing Abram to put his other plan into action, and Bloody Bernard, whom Abram called, spread terror as soon as he arrived and not only brought Saladin face to face with death, but also captured Damascus. Taking action to save Saladin, Sultan Nureddin manages to save first Saladin's men and then Saladin himself. While Sultan Nureddin and Saladin take action to save Damascus, which was terrorized by the Crusaders, they receive the news that Damascus has fallen. Moreover, Süreyya, Melike, İsmet, İlbüke, Rabia and Isfahani are captives in the hands of the Crusaders.
