Uğur, who rescued the children waiting to die inside, goes back a year to the man he met while the extinguishing efforts were still underway. Now he's got a lead on the fire that killed his wife. Uğur will fight relentlessly both to find the perpetrators of the fire in which he lost his wife and to bring him to justice, and to take his daughter Hayatm with him. Yonca, a court-appointed forensic psychologist, will be the most important person to influence the great decision when witnessing Uğur's war.

Uğur is very close to the men he thinks are trying to kill his wife. With the sudden death of Nazım, whom he is after, the crime remains. Caught between revenge and the promise he made to his daughter at the same time, will Uğur be able to catch up with Yonca and Ömrüm, who are waiting for him in the park?

Uğur, who is ready to give his life to reach his wife's murderer, will push his limits and come face to face with Yonca.

Uğur is aware that Tufan, who confessed to hitting and running with Nazım, is a big key to reach the gang that killed his wife. The risk he took to make the Tufan talk causes him to come face to face with Yonca again. Uğur now has to prove to Yonca that he is right... Uğur, who is not allowed to see his daughter, is in longing. On the other hand, Ömrüm is very upset that her father will not be able to attend the event at the school. Cem says he can attend the event as his uncle. This makes Ömrüm happy, even a little bit. Hearing the event at school, Uğur goes crazy. Will Uğur be able to go to school despite the ban, Cem and Yonca? Murat, who started firefighting under the protection of his father, strives to prove himself as soon as possible.

Zehra is furious when she learns that Uğur, not Cem, participated in the event at Ömrüm’s school. Fear of losing Ömrüm will make him make mistakes. He devises an evil plan to completely cut Ömrüm from Uğur. Yavuz, who likes to make friends with his enemy, makes a surprise visit to the headquarters.

Unwittingly, he began to feel a different kind of affinity towards Uğur, whom he helped professionally. Their feelings are never unrequited. The interruption of Yavuz’s plan will cause him to activate plan B. Yavuz again planned to solve all the problems from the arson work by using the money. However, his move causes Uğur to become even more ambitious instead of stopping Uğur. Uğur has discovered that the place where he can contact the gang is the kebab shop. He is about to risk losing his life, profession and everything for the sake of finding his wife’s murderer.

Unraveling the clues he caught one after another, Uğur took his breath in the enemy’s lair, in the kebab shop.

He has decided to talk to Menekşe and solve the problems, even at the cost of confronting his mother.

Emre, who is secretly following Uğur, will be in great trouble for him. In order not to lose Yonca, Emre shows her some video's, but her response was surprisingly not what he was expecting. Yonca, on the other hand, is stuck between her principles and emotions. If she turns Uğur over to the authorities she is certain that any chance of reconciliation with Ömrüm will be lost forever. Cem immediately notices Ömrüm's sudden interest in sewing. Cem, who has not seen her this happy before, thinks that it's necessary to make new decisions for her. For this cause, he will not hesitate to take the steps towards a deep crossroads with his wife Zehra.

As a result of the events he experienced, difficult times await Tolga, who broke down with Ayşe.

There's only one last step to pursuing of Uğur's wife killers. His journey, which he started with a spark, becomes a great fire and who else will he swallow?
