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.

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.

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.

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.

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.

Even though Gökhan disappears, Ömer is aware that this is not the end. The team's new goal is to prevent the company's money transfer and at the same time identify their new enemies. Defeated, Skarlet turns to those closest to her for support. As he enters Neslihan's life without being exposed, his partner will clearly become Ömer's target. New enemies, smarter and more ruthless than before, are aware that they are facing Ömer Atmaca and his team. No matter how much the company's new cell tries to hide itself and obfuscate, the Agency will find them.

Despite Cihangir being kidnapped, Ömer and the team do not submit to Anton. Neslihan is shattered by what Skarlet tells her. He confronts his father to learn the truth about his mother. Çetin is now backed into a corner. The target of Çetin's accusations is Ömer. Ömer does his best to both save Cihangir and reach Isis. The team tries to achieve Ömer's plan perfectly. Even though Anton and Skarlet think they have won, they will unknowingly find themselves in the game set by Ömer.

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.

Ömer goes after the mercenaries who came to save Cihangir. His goal is to find out who sent them. Realizing that Ömer will not let this matter go, Çetin is cornered. Cihangir, who burns with the fire of revenge because of his mother, finds Ömer in front of him. Ömer tries to prevent him from making irreversible mistakes. The team tracks down Anton, who lost both his brother and the company's money. Ömer is aware that Anton will make much more brutal moves.

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.

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.

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.

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.

Omar comes face to face with a new enemy. However, he realizes that this enemy is much different and, most importantly, more dangerous. Neslihan, who is completely cut off from Omer, tries her best to make both Omer and the team safe and sound. Omer will not give up until he gets his revenge no matter what. Even if he loses his life on this path, he will not bow down to the enemy.
