Ömer, devastated by Cihangir's death, challenges Anton, knowing that he will be set up. Ömer swears that he will take revenge on Anton and everyone who martyred Cihangir. Neslihan and the team, devastated by Cihangir's kidnapping, follow the clues left behind. They are sure that these clues will lead them to Cihangir and therefore to Ömer. The team, which does its best to find Ömer and Cihangir, is devastated by the message from Anton. Nothing will ever be the same again. The fire of revenge in Ömer's eyes will burn everyone in front of him.

Altay comes face to face with Berzan to take his revenge. However, Altay is unaware that his account with Berzan is not limited to the past. Selen, who is unconscious in Berzan's car, will turn all the truths upside down. Korkut manages to inform President Akif that the shipment is a trap, but he gets exposed. The opportunity Korkut has been seeking finally arrives. Even the enemy will willingly take him to the Queen he is searching for. The conflict between Altay and Neslihan continues with Altay's moves. With Kate bringing Selen, whom they thought was dead, to the forefront, Altay and Neslihan will find themselves on the brink of difficult decisions.

Ömer, who has one last target for Cihangir's revenge, takes action with the team to capture the Captain he is after. Having lost her brother, Neslihan does not want anyone to be harmed further. Ömer, on the other hand, is determined to catch his enemy. The two face each other again for their goals. Çetin, shaken by the pain of losing a child, takes new steps. Çetin, who blames Ömer for Cihangir's death, confronts Ömer. Ömer and his team, who are aware of the game played on them, do not give up until the criminals are punished. Neither Ömer nor the team will bow to the company's plans.

With the incident on the Mostar bridge, the enemy took action to create even more confusion. Milorad will target Ömer. Ömer, who puts his pain aside and fights for his homeland, will not remain silent to this challenge. Even though Ömer insists on going his own way, Neslihan's aim is to solve the problem at the table. Knowing that the slightest impulsiveness will cause greater chaos, Neslihan is determined to defend her country with evidence to the world. Gökhan, who has become the target of Ömer's suspicions, is frightened by Neslihan's determination, but will do his best to achieve his goal without giving himself away. The team does not leave Ömer and Neslihan alone in their fight from two different branches. Realizing that they have a lot to learn from each other even though they have just met, the team will be the reliable support of both their homeland and Ömer and Neslihan.

Ömer's only goal, considered dead by his family and loved ones, is to find Zehra. His efforts in this process introduce him to both his new enemies and Neslihan, who will bring him back to the organization. Neslihan's only goal is to keep her promises despite her losses and not leave the people who need her alone. However, even he is not aware of the dangers he will face. The biggest point that unites these two, even indirectly, is the love of the homeland and the desire to protect it. A new team fighting for the same goal will help them on this path. In this tough war, enemies are more dangerous than before. Although new beginnings, new goals and acquaintances lead the heroes to new surprises in the new season of Teşkilat, the only thing that does not change is the love of the homeland.

Serdar, who prevented the planned attack on the MIT building by plane, has disappeared since that day. Searching for Serdar everywhere in the intervening period, the team finally stumbles upon the traces of their lost friends in Poland and takes action. An unexpected person comes to the aid of Serdar, who is in a difficult situation, but Serdar has a big problem that will affect everyone deeply. On the other hand, the team has a new person to meet: President Halit. After Fadi's death, the company chooses a new name for the 6th Region, which includes Turkey. This ...

Altay, who does not allow Ejder to leave, faces Korkut. Korkut, on the other hand, has to make a big decision under the orders of Akif Başkan. Korkut, who needs to get Ejder out of there for the mission, shoots Altay. Although Korkut has saved Ejder, he is once again the target of suspicion. No matter what, Korkut, who has to cooperate with his greatest enemy for the sake of the operation, must not be exposed. Altay goes after Ejder, who escaped from his target. With the information he learned from the Machinist, the name of his enemy becomes clear to him. Altay and Neslihan, who want to reach the capsules, try to make the Machinist talk. On this path, Neslihan, who reaches important evidence, will face a devastating truth.

While Altay is chasing the capsules, he falls into the Queen's trap. Neslihan must make a difficult decision to protect the Protector. Altay, who does not know the reason for this decision, does not leave so many people to their fate. Ejder wants to intimidate Korkut. Korkut, who notices the bomb, must protect both himself and the people around him. However, the moves he will make while trying to defuse the bomb should not attract Hamdi's attention. Selen is beyond a terrible step under the manipulations of the Machinist and therefore the Queen. The move he will make may cost the lives of both his brother and the innocent people there. Altay, who will not bow down to the enemy, will do his best to save everyone from this trap.

As a result of the exercise, the success of the project is proven. In the next phase, it is aimed to eliminate any issues. Altay is assigned to learn the enemy's next move. By the order of President Akif, Korkut is dismissed from his duty. Although President Akif thinks that Korkut is torn between his emotions and purpose, Korkut is confident in himself. A message that Korkut receives will completely change the course of events. As a result of the tortures inflicted on Professor İhsan, Kate has learned the content of the project. The enemies plan new attacks. Altay and Neslihan's goal is to thwart these plans. While Altay and Neslihan progress confidently in their mission, the Queen sets dangerous traps for them. But Altay will defeat them no matter what.

Neslihan and Altay take a big risk in determining if their suspicions are correct. The moment they are attacked, they are sure that Selen is right. There is a traitor among them. Korkut's move dispelled Hamdi's doubts. However, to ensure his position, he challenged Hamdi. Although Korkut seems to have convinced Hamdi, those at the table will not let him go. Neslihan and the others conducted research to find Kate's agent in the organization. As a result of this research, the target will be someone very unexpected.

Due to the critical decision made by Neslihan to destroy the briefcase, Çanta ends up in the hands of the Makinist. Kate, who thinks she has reached victory, is left empty-handed. The teams can access half of the data in the briefcase with Altay's help. Güniz and Sedat, who are after Korkut's secret, bring Zeynep to Hamdi's house. Upon seeing Zeynep in front of him, Korkut realizes what Sedat is after. He must now act more cautiously to avoid being deciphered. To complete the data in the briefcase, Altay and Neslihan embark on a new path. Everything starts anew for them. As Altay goes into the field with Neslihan, the pain of losing his brother will challenge him once again.

As Neslihan rushes to deliver the antidote to Selen, the Queen’s men launch an attack on the clinic. Risking her own life to save Selen, Neslihan puts herself in grave danger, while Altay is willing to sacrifice everything to protect her. Following orders from Akif Başkan, Korkut sets out to track down the Queen, the mastermind behind Sofia’s murder. Cornered and desperate to remain unidentified, the Queen does everything in her power to stay hidden—but Korkut is closer than ever to confronting her. Meanwhile, thanks to Altay, the Organization uncovers the Queen’s latest schemes and is determined to dismantle them. Neslihan and Altay, standing by their decision, refuse to bow down to the Queen or her allies, no matter the cost.

As Altay confronts Selen, he finds himself facing a grave danger. Meanwhile, Neslihan is forced to shoot Selen in order to stop her. Korkut, determined to reach the Queen, sets his sights on discrediting Ejder as his next target, with Hamdi by his side to execute the plan. Fearing exposure, Kate relentlessly pursues Selen. However, Altay and Neslihan recognize that Selen could be their key to uncovering the true identity of the Queen. Yet, the biggest obstacle ahead isn’t just Selen’s gunshot wound—it’s something far more formidable. Their search for answers leads them down an unexpected path, bringing them face to face with a shocking figure.

The house the team infiltrated is ready to explode on Horus' command. Even though Gökhan's treacherous plan is for this explosion to happen from Neslihan's hand, Ömer realizes that there will be an explosion with a phone call. While Ömer has to fight alone inside, the rest of the team is waiting for a sign from him outside. Trying to access documents related to both Gökhan and the company, Ömer and the team duke it out with the enemies at the farmhouse. Even though Ömer is sure that Gökhan is Horus, Gökhan continues to confuse Neslihan. Under Ömer's leadership, the team always tries to be one step ahead of Horus and therefore the Company. While they find new clues on this path, they also encounter new enemies. The enemy's target this time will bring Ömer face to face with the past once again.

Although Gökhan, who uses Zehra and her pain, is sure that Ömer will make mistakes, Ömer will not sacrifice Zehra to these games no matter what. Faced with an unexpected move, the team is cautious to prevent innocent people from being harmed. Neslihan makes the biggest promise possible to both the minister and everyone else. Unwanted consequences may cost both Zehra's life and Neslihan's career. While there is a great struggle against time, Neslihan has full confidence in the team and Ömer. Ömer will not lose Zehra this time.

Anton falls into a trap with Ömer's unexpected move. Unable to risk losing his son, Çetin intervenes in his own way to save Cihangir. But thanks to Ömer's attention, he realizes that he cannot hide. Ömer's aim, who has planned everything meticulously from the beginning, is to both save Cihangir and deal a big blow to the enemy. No matter what, he will not bow to the enemy on this path. Neslihan and the team trust Ömer with both their homeland and their lives. That's why they take all risks to complete the operation successfully.

Altay, who is finally face to face with his sister whom he mourned, sees that Selen is the suicide bomber in Kate's treacherous plan. Neslihan is also aware that both they and the civilians around them are in great danger. Due to Suat's unexpected move, Korkut is on the brink of being exposed to both Hamdi and the table. He cannot afford for the operation to fail when he is so close to reaching the Queen. Having reunited with his sister, Altay will not lose Selen again, no matter the situation they find themselves in. Meanwhile, Neslihan will take great risks to save them.

Altay and Neslihan stand their ground against their enemies with a bold decision, but this choice also puts their lives in danger. Meanwhile, Korkut finally comes face-to-face with the Queen through his carefully crafted plan. However, Kate is far from pleased with this encounter and remains deeply distrustful of Korkut. Despite Akif Başkan’s warnings, Hamdi acts alone and falls into Ejder’s trap. Seizing the opportunity, Ejder plans to use Hamdi against Korkut. As Altay and Neslihan work to prevent uranium from being used against their country, they edge closer to the Queen. The clues left behind will be their key to uncovering the truth.

As the enemies are defeated one by one, new dangers continue to rise from the darkness. The Organization, which has consistently foiled treacherous plans, is now on the brink of a war greater than ever. With Eylül and Buğra joining the team, President Cevher's inauguration adds strength to their forces. This unity further intensifies the fight to uncover the enemy's true purpose, while Korkut is forced to confront the traces of his past on his own journey. As Altay takes action against the traps set by the traitors, he faces a name that will shift the balance of power: Rutkay's right-hand woman, Hilal. The shocking encounter between Altay and Hilal becomes his greatest test. As always, one step ahead of his enemies, the Organization is ready for any challenge it will face. But this time, the battle isn't just on the field; it's in the hearts of those who are.

Hearing the possibility that his sister is alive, Altay gets angry and threatens Makinist to find out what he knows about his sister. Neslihan, who thinks that Makinist's conversations are a game, is worried. She realizes what Altay is capable of when it comes to her brother. This situation brings Neslihan and Altay face to face. Having completed the first part of his mission, Korkut is now at Hamdi's house. Korkut takes his steps carefully and reports his condition at every moment. While the Neslihan's are after the stolen bag, the enemies are trying to find the code to open it. Altay will come face to face with danger as he aims to find out what happened to his brother.

Altay, who has seized the bag that everyone is after, is looking for an escape route. His goal now is to deliver the bag to the Neslihans. While the Neslihans are trying to find a trace of Altay, he is willing to put himself in danger once again to protect the bag at all costs. Upon finding Selen's message, Neslihan and her team realize the bag's importance once again. While Neslihan wants to retrieve the bag from the enemy, she also does everything she can to save Altay. With Hamdi’s move against the rivals, Korkut finds himself in danger. Although he feels uneasy knowing that his mission will also be at risk the moment things go wrong, he tries to remain calm.

Altay and Neslihan are shocked by what Turan, whom they knew as the Professor, said before he died. The real Professor is Turan's young son. The Machinist also hears this truth. To escape from the situation they have fallen into, Altay makes a dangerous move for both himself and Neslihan. When Korkut meets Akif, he realizes that he is being followed by Volkan. This situation poses a risk of exposure for both of them. Akif also understands that they are in a dead end. However, Korkut has a plan in mind. When Neslihan and Altay think their hopes are lost, they chase after the target again with the truth they have learned. Their goal is to find the real Professor before the Machinist and complete the important data for the state.

Neslihan and Altay are trapped by the Machinist together with İhsan Hoca. While the elevator is under the Machinist's control, Altay takes great risks to find a way of escape. Korkut does not give up on the trap set for him and Hamdi. He is determined to punish those behind it, but different challenges await him. Altay confronts his stepbrother Tufan, while Neslihan learns that İrfan Hoca knows Colonel Nazım. Although neither of them is aware, they will face their past. But no matter what, they will not allow the Queen to hinder them on this path.

Altay follows the clue he found, and Neslihan doesn't want to leave him alone. However, when Altay is incapacitated by a trap, he witnesses Neslihan being killed. Korkut learns that the person who ordered his sibling's death is Ejder. When Ejder comes to put Hamdi and those at the table in their place, he finds Korkut in front of him. This is the beginning of the war between them. While the Queen is trying to figure out Ejder, she is also pursuing the elimination of Altay, her greatest obstacle. Despite experiencing great pain, Altay will never bow down to the enemy.

Despite the Queen's efforts, Altay captures the Machinist. Now his main goal is to return to the country with him. Neslihan does everything she can to ensure Altay successfully completes this mission. While Korkut and Ejder are confronting each other, they face an unexpected visitor. Although this visit changes everything for them, Korkut is determined not to give up on avenging his brother's murderer. For Altay, bringing the Machinist back to the country will not be easy. While they are surrounded by enemies, the injured Machinist's condition is not good. Altay will take great risks to access important information through him, but he will not be alone on this path.

After Altay learns that Ejder is behind everything, he is now after him. Korkut must stop Altay without revealing himself. To get closer to the Queen, Korkut must be willing to make some sacrifices. As situations become increasingly difficult, Ejder’s move will force Korkut to take great risks. Neslihan learns that the strands of hair in the Machinist's possession belong to Selen. She must be sure of her suspicions before telling this devastating truth to Altay. Altay and Neslihan obtain new clues about the Queen. A new danger awaits the duo who go to Monaco for the operation. Altay will once again face the fear of losing Neslihan.
