Ceylin and Ilgaz, a prosecutor and lawyer, are two people of law whose methods are on opposite poles while they are fighting on the same path. Endlessly clashing and testing each other until they come together to fight a common battle. When Ilgaz catches a murder case in which his brother ends up involved, he must work together with Ceylin to solve the case.

The Erguvan family is shattered by the death of their little girl. It is Ceylin's duty to endure the pain of her mother, sister, and father, in addition to living through her own pain whilst fighting with the last drop of her blood to find her sister's murderer. With every piece of evidence, a new suspect is added to the list. The questions are increasing.

Witnessing Zafer's interrogation, Ceylin is faced with facts about İnci that she cannot handle. As both Ilgaz and Ceylin implement their own plans, the sense of trust they are trying to cultivate against each other will be tested again. Trying to reach the truth brings them closer over time, and causes walls to rise between them and their families. Will they be able to stand against these walls without collapsing?

It is now known that the person who killed her brother is Engin, and Ceylin is in indescribable pain. The anger rising in her is unbearable, and Ceylin is determined to kill Engin. Although Ilgaz is right in his intuitions, he cannot stand Ceylin's collapse and makes a decision. He finds his own way, albeit harshly, to calm Ceylin down so that they can prove that Engin is the killer. Pars is determined to put aside even his feelings for Ceylin and accuse her of collecting evidence irregularly and ban her from the profession. Ceylin comes face to face with Ilgaz. While Yekta struggles to clear his son's name, Zafer is devastated by the release of Çınar and comes to the brink of a new turn. His decision will change the fate of the two families forever. While Ceylin and Ilgaz are chasing the evidence that will convict Engin, they also look for ways to get out of the difficult situation that Pars has put them in. Will Ilgaz give up on his own rules and lie for Ceylin?
