Osman was defending his city against the Mongols and took control of the captives. After hearing that Aktemur was declared the new Bey, Osman calls for a meeting. Meanwhile, Nayman orders his soldiers to sneak into the forest, and Malhun and Aisha warn Aktemur about the potential danger. Despite the warning, Aktemur attends the meeting and stands by his decision. However, during the meeting, the vizier catches Bala and threatens to execute her.

Ismihan intervenes and reveals that the vizier is a traitor who was planning to have Mongolian soldiers attack and kill the Sultan. The Sultan executes the vizier and listens to Bala’s information. Osman discusses how to defend the cities with the Beys and promises to help the people. He then expels Aktemur from the meeting, stating that his decision was wrong. At Bala’s request, Sultan writes a letter to Gazan, and Turgut catches Bayindir and speaks with Talay.

Bengi convinces Aktemur to avenge Oktem and attack Marmaracik. Meanwhile, Gazan’s commander arrives and takes Genghis’ seal from Talay, who is sceptical of Turgut’s claims. Later, Osman dines with a merchant and goes to the mosque to pray. He also talks to his children. Meanwhile, Aktemur secretly meets with Malhun in the forest and prepares to attack the castle, believing that Osman is aware of everything.

Nayman takes the poison prepared by the shaman and goes to the battlefield, where Osman chooses three Turkish soldiers to duel with three Mongolian soldiers. Ultimately, Osman fights Nayman and is blinded in one eye by the poison in Nayman’s ring.
