Devran, a math genius, plans to go to America with Esme after receiving a scholarship. His father Iskender abandoned them years ago. Devran wants Iskender to know his success but keeps him away from family.

Devran plans revenge against his father, involving Iskender unknowingly. Cesur gains leverage over Hakim. Despite Esme's concerns and Sofi's advice, Devran persists. Iskender encounters surprise due to trusting the unknown Devran.

Devran's quest for justice goes awry when Iskender's return disrupts everyone. Forced to cooperate with Iskender, Devran faces brutal consequences. Gülce confronts trauma while opposing Aysel's plans. Esme warns Devran harshly.

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.

The family is horrified when they see the new owners of the house, but the Karga threat to Devran forces Gülce to turn a blind eye to this situation. 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.

When Devran loses Çaglar, he finds himself in the unknown again on the road to Boran's murder, but now he is sure of Cesur's connection with this murder. Realizing that he should no longer act alone, he decides to change his method and asks for Sofi's support. While Iskender is about to tell Karga that he will not work with Devran anymore, Devran's unexpected move prevents Karga from giving up on him. Yaman, Ferman and Ceylan begin to be tested with money, Esme is aware of this and warns Devran about this. Devran, who is trying to get everywhere, makes an unexpected request from Karga with his plan.

Iskender starts working with Ferman for a flashy opening. Imre, on the other hand, has already started to confuse Ceylan by showing her his own world. Devran realizes this and after talking to Imre, he realizes that it will not be easy to stop Iskender from infiltrating his family, and he sets out to sabotage the opening by devising a new plan. When Hakim learns that Karga has decided to take a closer look at Boran's murder, he pressures Cesur. At Iskender's request, Cesur opens the path where Devran put stones, but this is not enough to stop Devran. A big surprise awaits Devran and his family, who gather everyone together to meet Iskender on the opening day.

İskender cornered Devran by taking Ferman with him. Devran, planning to defeat İskender without harming Ferman, uncovers his latest scam with his intelligence. However, instead of confronting İskender directly this time, he takes a very different path. While asking Karga for help in finding Boran's killer, he also discovers a way to corner him, thanks to Imre. This, however, leads to a confrontation with Imre. Cornered, Karga comes face to face with İskender due to Devran's move. Although both Cesur and Hakim try to neutralize Karga as he gets closer to Boran's killer, they realize they underestimated his power. Thanks to Karga, Devran not only puts İskender in a difficult position but also remains one step away from Boran's killer.

Devran arrives at the house where Boran was killed and encounters someone waiting for him there, falling victim to a setup and getting arrested. However, he turns this situation to his advantage in a way that allows him to find the real killer. With the bait he sets for Iskender, Devran starts to piece everything together. Once everything is complete, he is no longer the old Devran. But with Sofi's support, he acts strategically without succumbing to his emotions and ensures a major confrontation with Iskender and Hakim at Karga's house. However, he is not satisfied. He will make sure everyone responsible for Boran's death pays a price. He starts with Iskender.

Iskender survives the fire, but he must now comply with Karga's new ultimatum. Ferman uses his signature powers to shut down the company, preventing his father from escaping with money and Aysel.

When Aysel falls prey to Iskender's self-serving actions, Imre shifts the blame onto her brother, Cesur. As a result, Iskender is now determined to pursue vengeance for the woman he loves. Karga recovers control of the family business.

Ihsan's move revealing Cesur's involvement in Boran's murder drives Devran mad, but one of the things that accelerates his harsher actions is the unexpected burden of conscience caused by the revenge he took on Karga. This burden causes more tension with Sofi. However, Sofi, due to a past that unexpectedly confronts her, is forced to understand Devran. Along the way, Devran searches for Cesur, but a promise made by Iskender requires him to find Cesur before Devran. With the plan he devised, Devran surrounds Cesur from all sides. The last resort Cesur clings to appeals to Esme's conscience.

Devran confronts Esme and tells her the truths about Cesur. What Esme has been hiding from him creates a rift between the two. When Karga enters and Devran learns that Hakim is alive, this time he does not leave his revenge to chance. When he comes together with Iskender once again for a common purpose, this time it is Devran who tricks him. Moreover, Ferman and Yaman have also joined the plan. Cesur's effort to make a place for himself causes Devran to become even more determined, and he brings Ihsan upon both Devran and Iskender. This time, Ihsan is determined to hit them where it will hurt the most.
