Faysal publicly implicates Hakan in the Hagia Sophia incident. A grief-stricken Zeynep confronts Derya and learns about an imminent attack in the city. Hakan finds a link between the museum robbery and the Immortals’ lethal plan. Struggling under Faysal’s influence, Leyla puts Hakan in danger. Zeynep enlists Leyla’s help in pinpointing the Immortals’ target for the attack. Faysal goes after Hakan as Rüya’s condition deteriorates. Hakan and the Loyal Ones hatch a scheme against Faysal, who uses Leyla as a bargaining chip — but a shocking betrayal derails the plan. As Hakan scrambles to find Levent and put a stop to his vindictive crime spree, another Immortal takes control of Leyla’s mind. Tensions come to a head between Faysal and Rüya, who conspires with Mergen against Hakan. Leyla’s fate hangs by a thread. Rüya uses Levent as a pawn in her masterplan. Zeynep and Azra learn that the talismanic objects are losing their powers. The Oracle tells Zeynep and Hakan what it would take to restore the powers of the talismanic objects. Blood is shed on both sides in a vicious showdown.
