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.

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.

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.

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.
