Episode 3
While Hamburglu’s proposal is openly discussed within the family, the fact that Bozo is waiting for the “sign that will come from the underworld” gives the sense that the approaching war is only the visible part of something much bigger. On the state front, Aslı cornering Pınar makes the balance even more unstable, while the shadow of the word “betrayal” begins to circulate between Ceylan and Bozo. The unexpected deal that Sultan makes with Haydar Ali and the shocking confrontation experienced during the night ignite the fuse of a rupture that will affect not only two young people, but the fate of two families.

While Bozo is in custody, discussions about leadership within the family intensify. Merdan puts his own plan into action, and Haydar Ali decides to take control once and for all. The secret message sent by Bozo, citing four names linked to the betrayal, completely changes the balance of power. At the same time, a shadowy business network with connections in Malta emerges. On the police side, covert maneuvers conducted through lawyers make the confrontation in the underworld even more complex. The major turning point occurs when Ceylan, alongside Gülsüm, goes to Azize's house and openly declares war: "Since you started this war, you will face the consequences." Amidst love, loyalty, and the struggle for power, Haydar Ali embarks on a path of no return, trying to keep the family together while seeking to discover who the true enemy is.
Episode 5
The fact that Bozo throws himself in front of the bullet for Haydar Ali turns everything upside down in Yeraltı. The bullet may have missed its target, but the score has not been settled. Caner is captured, Zafer is summoned, and a single question hangs before everyone: Will this end here, or is the real war just beginning now? Bozo’s decision seems to contain the bloodshed, but some are ready to interpret this calm as weakness. While Haydar Ali finds himself torn between debt and conscience before the man who risked his own life for him, Ceylan tries to uncover the real reason behind her husband’s sacrifice. Sultan faces her own past one last time and closes certain doors once and for all. On Paşa’s side, a crisis on the verge of exploding and an even bigger plan being set in motion behind the scenes.
Episode 6
The bullet that hits Pasha in the chest targets not just one body, but the entire family. While hope and fear intertwine in the hospital corridors, Bozo's cold and harsh demeanor shocks everyone. As Ceylan tries to keep the family together, Sultan's digging into Haydar Ali's past in the hospital corridors brings the "ex-lover" issue back to the forefront, igniting a hidden tension. As questions grow about whose orders Pasha followed that night, the fire of revenge spreads rapidly through the neighborhood. Haydar Ali, believing Pasha didn't act alone, decides to uncover the truth. Gunfire in a house in Tuzla changes the course of events. The actions of Ferhat Bozo's impulsive cousin, Derman, instead of covering up the truth, open the door to a bigger confrontation. Yavuz catching them red-handed brings the reckoning directly to Bozo. This time, the war is growing not just in the streets, but in people's hearts. And Bozo's decision will reveal who the real enemy is.
