One week before his graduation, Sarp Yılmaz, the valedictorian of the Police Academy, is forced to confront his father's dark past. He does something he should never do and his life is turned upside down. Commissioner Mert Karadağ, who graduated from the Academy, starts his duty in the Organised Branch and finds his term mate Sarp Yılmaz as an enemy.

Sarp loses control when he catches a clue that his brother, whom he thought was dead, is alive. He comes to the point of giving up on the plan he and Yusuf Warden have devised. Either he will track down his brother as a mole and try to find him, or he will lose his anger and confront Celal, the Kebab maker who kidnapped his brother. On the other hand, Mert starts to get dangerously close to Füsun, who he does not know is his mother, and Eylem. The secrets of Mert inside the police and Sarp inside the mafia are gradually revealed.

On the night Ömer is executed by Davut, Sarp is forced to shoot himself in the shoulder to save Commissioner Mert's life. This situation has to remain a secret between Mert and Sarp. While Mert escapes and tries to save himself, Davut leaves Sarp, who is wounded, to die in the forest that night. At the last moment, Sarp, who thinks that he will die in the forest that night, receives a helping hand from someone he never expected. Alyanak suspects that someone is helping Sarp who comes to the car park wounded. Füsun searches for Sarp all night but cannot reach him. Worried that something has happened to him, Füsun ends up at Alyanak's car park. They hide Sarp's injury from Füsun. Kebab maker Celal has Sarp treated in a secret lake house. An emotional rapprochement begins between him and Melek who does not leave him alone.
