While Mete is undergoing emergency surgery, Serdar, who, despite his best efforts, could not prevent the assassination, is shocked by the incident. Although the team managed to escape the ambush set up by Fadi, Mete was shaken by the news of the attack on the President. The team meets at headquarters and rolls up their sleeves to avenge Mete.

Fadi, who understands the team's game and is surprised by what happened to him, will be in danger of losing his position! Disrupting Fadi's plans, the team returns to the country to rush Hulki, whose condition is getting worse, to the hospital. Fadi's failure causes a great deal of discomfort at the Company. Cornered by the Company's decision, Fadi takes one last chance to prove himself. Suspected of loyalty, Ceren receives instructions from the Chief to kill Serdar. Meanwhile, a video circulated online causes a stir. The teams is on high alert against a planned assassination plot against a senior government official in Ankara.

Ceren, who was surprised by Serdar's announcement of his identity and proposing to her, doesn't know what to do about this surprise move. A mysterious name from her past helps Ceren, who is confused by this movement that reaches the end of the road... Zayed Fadi is cornered when the team takes over Leyal, his most trusted member.

As the team tries to get Hulki out of the trap, they come across a much bigger threat.

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.

Zayed Fadi, whose plans were disrupted by the team's operation, wants revenge. Fadi's putting Serdar at the top of the list of those who will be destroyed! He's mobilizing his men to see if Serdar has left Berlin. Serdar convinces Fadi and his men that he has left Berlin. With the intelligence it has obtained, the team is moving to prevent Fadi's provocations. The fact that Serdar and the team did not leave Berlin and disrupted all the plans puts Ceren in a difficult position. Ceren now has to prove himself again to Fadi. Neo-Nazi groups are attacking expatriate Turks in Berlin with the support of Fadi's men. The team is setting up a dangerous game to prevent these attacks. Serdar infiltrates neo-Nazis under a different identity. Serdar is under the influence of past traumas in this difficult task. Trying to prevent provocations against expatriate Turks, the team is plunged into an international crisis.

Serdar, who suffers from the biggest shock of his life due to his beloved Ceren being a traitor, is questioned by internal affairs while thinking about how he came to this game. After the plane crash, with the official announcement of the death of the members of the team, the families go to Mete's side. While Mete gives the bitter news to families, team members who cannot communicate with their families. Serdar, who came out of the internal affairs inquiry, has to continue his relationship with Ceren on the instructions of Mete. While the team works hard to track down Pascal, who organized the SİHA attack, Serdar, who came to the secret headquarters, meets the team members. Upon the information that Pascal will flee abroad, the team takes action for their first operation. Vowing not to leave the blood of the martyred engineers on the ground, the team is determined to catch Pascal and reach the dark structure behind him.

A dark structure acting against Turkey targets Turkey's UAV and SIHA program, which attracts international attention by commissioning its plans. After this surprise move, a decision is made to create a secret team under the umbrella of the National Intelligence Agency. While this team, led by experienced intelligence officer Mete Bey, is planned to carry out many covert operations at home and abroad, it is necessary that the team members are officially dead. Mete Bey meets with Zehra, Uncle Hakkı, Pınar, Hulki, Uzay and Georgan one by one and tells each of them that everyone who knows them and their families should consider them dead. For the leadership of this team, which brings together the best intelligence officers of the organization, the most popular name of the organization is Serdar Kılıçaslan. While Serdar remains between his love for homeland and his love for Ceren, the other members of the team realize that they will go on an irreversible path.

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 ...

Serdar still has difficulty believing in the love game he is drawn into. On the other hand, he wants to take back the external disk containing the SİHA protocols, which were seized by the killing of the country's pupil engineers, as soon as possible. Serdar sets a deadly trap by getting help from Zehra. Although it irritates Zehra, the trap works, and the war between Ceren and Serdar is getting hot! Those who died before they die, on the one hand, try to cope with the fact that they are unable to reach out to them by following their families' experiences in the face of their loss from a distance. But, on the other hand, in this game, in which they risk everything with their love of their homeland, they are now pursuing those who order an attack on the SİHA factory. An established game opens the door to reaching the “company”, which instructs Pascal to attack. This door leads our heroes first to Berlin, then to a bargaining table in Berlin, where there are enemies from many countries.

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.

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.

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.

Cevher President’s decision about Altay and Hilal takes the two by surprise. When Hilal opposes the decision, she faces Cevher President’s harsh reaction. While she is caught in a major dilemma, Altay does everything he can to remind her of the importance of their mission. Although Korkut’s plan to use Ejder is risky, he takes the gamble with Cevher President’s approval. Meanwhile, in her moment of desperation, Bahar once again turns to Korkut. As he helps her, Korkut remains cautious about her past. Altay, on one hand, tries to eliminate the Dizdar threat, and on the other, prepares for a larger plan. This plan will lead to an important encounter—and the balance of power will shift.

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.

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.

Altay finally learns that the Queen is actually Kate. While he grapples with this shocking truth, Korkut’s life is also in grave danger. Altay and Neslihan, shaken by the revelation, quickly realize they must focus on helping Korkut. Kate, unsure of Korkut’s loyalty, begins to see him as a threat. In an effort to earn the Queen’s trust, Korkut is prepared to take a huge risk. Meanwhile, Kurtbey and Fırtına will finally come face to face. As they join forces to crush the enemy from two fronts, this powerful alliance is set to shift all the balances.

Although Neslihan's arrival at the invitation drags the team into unexpected situations and emotions, Ömer keeps everything under control with his professionalism. Because of his sister, Cihangir is the person who has the most difficulty in this situation among the team. But both he and the other members of the team will learn to control their emotions on the field under Ömer's leadership. While Gökhan tries to confront Neslihan with Milorad, he also maintains his considerate attitude towards Neslihan. Ömer, who does not fall for Gökhan's games, is trying to prove his true identity first to Neslihan and then to the whole world, no matter what. Trusting Ömer's knowledge and foresight, the team will do their best to successfully complete the operation, capture Milorad, and learn the true identity of Horus, despite the sudden surprises they encounter.

Gökhan is sure that he will get away with what he did. But the team is always one step ahead of Ömer with his plan. Neslihan constantly comes across her father's name on matters related to the company. The new fact he learned is that Çetin is the clear target of the company. Scarlett, who is no longer in Gökhan's shadow, will not hesitate to make moves to eliminate Neslihan and her relatives. Ömer aims to bring Gökhan to Turkey and punish him before he causes a crisis abroad. The team that follows his instructions to the letter is always prepared for any problems that may arise. Both Gökhan and the company will always find Ömer and his team in front of them.
