The Oath

Derman has become a major threat to Turkey, the last to come to an order to turn to detained Attache. Despite the foreign state authorities' durability, Derman, who took the Attache from their hands, will continue his decision with Attache for the big terrorist act. The Medusa Plan is now governed only by a route they know. Eylem, Avci and Karabatak are appointed to reveal the secret headquarters where all information about the Medusa Plan is kept. A treacherous trap expects Eylem, Avci and Karabatak, who reaches the region at night. This trap brings Avci face to face with death. Having spent a surprise night full of danger with Bahar, Yavuz takes action to fulfill what his father Agah wants from him. As soon as he is aware that Avci's life is at stake, the team in Yavuz' administration goes out on the road and enters a great struggle to take out Eylem, Avci and Karabatak from the dangerous situation they are in.

Yavuz and Derya are trapped and in order to get out they have to go against Dragan and his men. But Dragan does not intend to give up, he attacks more violently and takes Derya as a result of this attack. Team, who came in prison for Karabatak, finds themselves in another dead-end. Because Dragan, who learns that the team is inside, raid the prison. Dragan, who has trapped Derya and the team together in the prison, wants Orhan. Yavuz sets out to save Derya, but doesn't know that the team is also in prison. Yavuz, with the help of Kopuk and Turan, takes action to take Derya, but following the treacherous plan of Dragan, he has to make a difficult choice between Erdem and Derya. On the one hand, is the life of his commander, on the other hand the life of the woman he loves.

After the ceremony in Battalion, noticing the surprise Ali Haydar made before he died, the team drowned in tears. But the memories of their friends will no longer be erased for a moment. Team, who has been sending Ali Haydar for his eternal journey, now has a single destination; Ali Haydar's blood is not left on the ground, asking for account from its killers - Karabatak goes on a very risky basis to determine the location of the killers with a secret duty, but Karabayir still lives in spite of everything. With the Turkish Red Crescent who wants to send aid to the civilian people in the regions that are provided security beyond the border, Bahar, Guler, Su and Nazli goes with them. The attache, who is aware of this, assigns Derman to stop the convoy. Derman attacks the convoy with a treacherous plan and everyone's life is in danger. Yavuz and the team, who are after Hafiz's assassins on the way to the convoy, are too late for anything when they get the news of the attack.
