Gaddar

Dağhan is the eldest of a family of three children... He lived a modest life with his family in a middle-class neighborhood. One day, after a violent argument with his father, Dağhan decides to join the military. About to return, he learns that his lover, Aydan, has participated in a beauty contest without his knowledge. Unable to control his anger, he breaks up with Aydan and joins the special operation. After some traumatic events, he returns to his hometown. But he can't find anything as he left it. His estranged girlfriend, Aydan, has disappeared. His family is dispersed... Things in the neighborhood are not the same, bad people are around, his old friends are involved in illegal activities. In a chaotic environment, a type called Manager also emerges. He offers Dağhan a job. Dağhan vehemently denies it. But while trying to protect his best friend Samet, he finds himself in the middle of trouble. He realizes that he must be ruthless to keep his loved ones away from this trouble.

Dağhan decides to do the job given by the Manager in order to protect Samet's family and comes to Yüksel's house, but he encounters someone he never expected, Aydan, his girlfriend from whom he broke up. While trying to get over the disappointment, spooky people raid the house, and Aydan and Dağhan find themselves in the middle of danger. While trying to escape this danger, they desperately try to repair their shattered love. Dağhan is busy gathering his dispersed family on the other side. He picks up Rüzgar, who got into trouble and was sent to the police station, and takes him home, trying to reconcile him with his father. Gürkan is almost sure that Dağhan has something to do with Samet's death and does not let go. While Dağhan was dealing with the new task given by the Director, he learns that Zafer, whose brother he killed, escaped from the hospital and goes after him.

Dağhan returns home to find his father unconscious and his mother and sister at the mercy of Zafer's gun. While Dağhan tries to get rid of the trouble caused by Zafer, his family learns that Dağhan killed Zafer's brother during the events. Dağhan seeks help from his father, but Davut is torn between his son and his conscience. Although Aydan resists not betraying Dağhan, the anger between them never subsides. Aydan doesn't leave Şengül alone. Samet's brother knocks on Şengül's door, attempting to forcefully take Umut, whom he considers his brother's legacy, from Aydan and Şengül. This ambition puts Umut in danger of losing his life. Dağhan is worried because he can't find Yağmur. He starts investigating in the hope of getting some news. Meanwhile, Enver begins to chase Dağhan, the man who not only killed his partner but also managed to disappear skillfully.

When Dağhan goes to kill Enver, who is the biggest risk for his family, he encounters a surprise he never expected. He learns that his sister Yağmur is with Enver. Yağmur gets sick because of the tension between Enver and Dağhan. Two enemies trying to kill each other are forced to team up and try to get her to the hospital. After the recent events he experienced, Dağhan's psychology deteriorates further. Moreover, there are things that both his mother and father are hiding from him. He becomes unable to trust anyone. Aydan also has a secret that she is hiding from Dağhan. Hoping that things will get better between them, she makes an offer to Dağhan. Ekber has now learned the secret that Enver persistently kept. His father's reaction is harsher than he expected. The showdown between father and son escalates. On the other hand, Şengül has now returned to her home, but the landlord wants to evict them because she cannot get the rent. Aydan does not like Dağhan spending time with Şengül.

Dağhan learns that the director sometimes sets targets independent of the Company, and these targets are always bad guys. This situation puts Dağhan at a new crossroads, as he begins to take pleasure in helping people in need and punishing the wicked. His relationship with the director, which he is forced to continue, takes on a new dimension. While Dağhan is pursuing his new target, Enver is trying to set a trap for him. He cannot directly attack Dağhan because of his promise to Yağmur. Therefore, he tries to prove that Dağhan is a hitman. On the other hand, defying his father, Enver hastily decides to marry Yağmur. Ekber Baltacı's strong reaction to this decision puts the two families against each other. The second part of Enver's plan to destroy Dağhan involves Aydan. He tries to persuade Aydan to join his side and get information about Dağhan from her. Aydan's mother, Oya, also supports her daughter's efforts to help Enver and puts psychological pressure on her.

Dağhan is cornered by the trap set by Enver. Gürkan has now learned that he is a hitman. But Dağhan chooses to fight instead of running away and hiding. It is time for the Director and Dağhan to clarify things. Dağhan starts looking for the murderer of the taxi driver who was killed in his neighborhood. While tracking the killer, he crosses paths with an old friend. Realizing that his son will not give up on Yağmur easily after his last actions, Akbar threatens Davut. On the other hand, the tension between Ekber and his son, who takes action to separate Enver from Yağmur, becomes even more dangerous. The solution Enver finds to get out of this situation drives Akbar crazy. Akbar, who said that he was not a monster until now, has now reached the point where he can do anything. No matter what, Aydan is still hopeful of reuniting with Dağhan. Oya thinks that this hope has ruined her daughter, so she tries various ways to save her from the love of Dağhan.
