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.

After what happened to Esme, Devran, who is going through a major crisis, is facing a threat to his health, but he does not give up on taking revenge for the game Ihsan played on him. To take revenge for both himself and Sofi, he collaborates with the police. This collaboration leads the police force to approach him with a big offer. Having just returned to university, he accepts this offer because both Ferman and Yaman fall into Iskender's trap and are burdened with debts. Because now time is limited for Devran, and he needs to embark on a path from which there is no turning back.

When Cesur realizes that Devran has managed to save himself with a nimble maneuver that he thought would throw him in front of Kuduz, he decides to intensify his moves. Devran is aware that the maneuver he used against Kuduz is dangerous, but he is also confident in himself. Both Cesur and the police are on his tail at the same time. Moreover, if this maneuver fails, the Kuduz family will come after him. As Devran and İskender act together against him, they engage in a dangerous game. With the support of Yaman and Ferman, they manage to escape at the last moment. Thus, Devran succeeds in turning the Kuduz threat to his own advantage. However, the secret information Cesur has given to Kuduz presents Devran with a new challenge.

Although Devran manages to escape the hell Kuduz left him in, the trace left unnoticed causes Chief Faruk to pursue the tip-off made by Cesur. While trying to get rid of the gold without getting caught by the police, Cesur doesn't stay idle and makes a move that touches Yaman. This situation takes the relationship between İskender and Yaman to a different level, while Devran very harshly proves what kind of person he has become after what happened to his brother. During this process, Imre, who has to confront his illness, also helps him. As Devran reveals the surprise he prepared for Cesur, he is in for a much bigger surprise related to the murder he thought he had escaped.

While Devran plays his biggest card against Cesur, Cesur is trying to survive. He follows the clues with a major piece of information he learned from Sofi and corners both Devran and Kuduz. However, Devran pays the price for blowing up Yıldırım's place with İskender. The plan he devises under the pressures from both İmre and Kuduz surprises everyone and also teaches İskender a lesson. But none of this can prevent Devran from being Sofi's biggest disappointment.

Devran and Kuduz are saved from the police investigation thanks to İskender. As Devran begins to question why İskender has done him this favor, he also tracks down the missing Karga. With İskender’s support, Devran rises in the gold business and starts to trust him more. However, İskender is also plotting his escape from the Altay murder, aiming to kill two birds with one stone. Aysel, as usual, gets involved in İskender’s plan in her own way. Despite the warnings from İskender and İmre, Devran stands on the brink of making a huge mistake.

After the major betrayal he suffered from İskender, Devran is now more ruthless. Moreover, his trust in İmre is shaken. While fighting for Devran, İmre finds himself in a great dilemma. Within this dilemma, he manages to convince Devran of himself. While Cesur and İskender are trying to eliminate one of their partners, they unknowingly use Devran. During this time, Devran experiences a significant loss, and when he realizes it was because of İmre, it is already too late for everything. When Devran finally decides to be İskender's downfall, someone he never expected executes the move he had in mind before him.

Knowing that Devran will take action to protect his mother, Sofi moves first—to protect Devran. Both Gülce and Devran are under serious threat, and Sofi is determined to shield them from harm. Meanwhile, as İskender hovers between life and death, Devran devises a two-pronged strategy, preparing for either outcome. Anticipating İskender’s survival, he sets his plan in motion by tightening his grip on Kuduz, leading him to a mysterious figure known as Karahan, the "Jeweler." This bold move forces Devran to take a significant risk, but he refuses to leave anything to chance. Determined to strike İskender at his weakest point, Devran decides to target his greatest vulnerability—Aysel. However, İskender, unwilling to be outplayed, finds a way to survive and turn the tables on Devran. But Devran is always one step ahead—and this time, he is willing to go further than anyone could have anticipated.

After Devran's last goal, İskender doesn't stop. The father and son, who start to exchange their cards, include Karahan in their conflict. Karahan, however, is more interested in İmre than in İskender's debt to him. But he has also made İskender dependent on him. While İskender tries to stay close to Devran, Devran has to meet with İskender one last time for Karahan. However, at the end of this encounter, İskender, as always, tries to throw Devran in front of Karahan ruthlessly. As Devran tries to get out of this situation, he sacrifices a name that is also a surprise to İskender.

Devran discreetly takes action on multiple fronts to take everything from Iskender, as he promised. First, he uses his intelligence and then his persuasion skills to make Iskender fall victim to his own greed, taking everything from him and causing Iskender to lie to Aysel. When Karahan learns the reason why Imre agreed to be with him, he makes her an offer. Disappointed by Devran, Imre collaborates with Karahan. However, Karahan has a different surprise for Devran beyond this collaboration. Yet, Devran is not surprised by this surprise.

This time, both Devran and İskender must fight for the women they love. However, İskender also sees Devran’s struggle as an opportunity to turn the situation to his advantage against Karahan. Cesur realizes that, with this move, İskender might even be willing to sacrifice İmre for money, leading him to take an unexpected step to protect her. As Karahan finds himself cornered by Devran, he becomes even more dangerous for İmre. While Devran tries to save İmre from this threat, İskender prepares to strike Devran where it hurts the most in order to win Aysel back.

The more Devran tries to save İmre from Karahan, the deeper he sinks into even greater dangers. While fighting to protect İmre, he also faces a tough choice—he must give up a crucial bargaining chip in order to save Gülce from the murder charge pinned on her by İskender. Meanwhile, Karahan corners Cesur in his search for İmre, ultimately forcing İmre to make a life-altering decision about Devran. As a result of this decision, Devran learns a shocking piece of information from Cesur—one that pushes him over the edge and compels him to take bold and reckless action.
