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.

Sarp goes to the neighbourhood to confront Celal to save his family. Melek is the only trump card he has. Mert is very upset because he caused Füsun and Eylem to be kidnapped. He makes a plan to prevent any harm to them. He takes his team secretly from Yusuf and goes to the exchange place of Melek, Füsun and Eylem. When Yusuf finds out about Mert's move, he gets very angry that something is being done without his knowledge. Not only Celal and his men are after Sarp for Mestan's death, but the police are also after Sarp. Sarp has to clear himself without getting caught by anyone.
