Devran, who is trying to take precautions for the leverage he gained after Iskender was shot, attempts to launder the money piled up in front of his house, with the uneasiness of knowing his father so well. On the one hand, he takes action to prove Iskender's connection with Boran's death and asks Esme for help with the evidence he obtained. After his forced partnership with Iskender, Devran is forced to involve the locals in the money laundering business. Iskender makes a new move to secure himself, but this time Devran takes his steps much more firmly. When the money was transferred to Karga's account, Devran not only avenged his mother's past revenge but also managed to introduce evidence that would disturb first Cesur and then Iskender.

Devran's victory creates such a rout in Iskender that this time he decides to give his son some harsh fatherly advice. When Devran thinks he is the closest to Boran's murderer, he is shocked by Cesur's move without anyone noticing. When Devran, in the enthusiasm of victory, is forced to invest his last chance in an option that he sees at the end of the rope, it is Iskender's turn to give a lesson. This time, Sofi is the one who passes the paternity test and rushes to Devran's aid, but Iskender is not finished with Devran yet.

Devran decides to act in a more planned manner after Iskender's betrayal and starts working with Karga again. Devran manages to track down Boran's murderer and remind Iskender of himself at the same time. In response, Imre also enters the game and takes action to hit Devran from the point where he says he is strongest. Thereupon, while Devran is in the middle of a great chaos, he receives the news from Tim and the evidence that Cesur hid from him.

Having come face-to-face with his brother's killer, Devran realizes that Cesur is far more entangled in the situation than he initially thought and confronts him, though he's still distant from the killer himself. When Iskender learns that Karga has invested in Hakim's failed company, he worries that Karga will no longer work with him and blames Devran for this setback. Deciding it's time to find a new partner, Iskender plans to exploit the vulnerabilities within Devran's family. As Devran tries to close in on his target by pursuing Cesur, he also attempts to rescue Ceylan from her dilemma, but Iskender is already fueling these conflicts. Seizing a brief moment of weakness from Cesur, Devran embarks on a path from which there is no return.
