Prosecutor Leyla Gediz, who has just returned to Istanbul, is unaware that the case she took on the first day and the man she met the same day will change her life. Leyla takes charge of a murder case that shakes the whole of Turkey. Leyla, who even disregarded her brother who committed a crime in the past, will receive an unexpected blow when the names of the people she trusts the most in life are mentioned in the case and she will have to question who she can and cannot trust. Turkey's most popular news presenter, Kenan Öztürk, is the son of Chief Prosecutor Turan, to whom Leyla is affiliated, and he is closely interested in the same case. Kenan and Leyla, whose destinies constantly intersect, will have to resist the attraction between them and walk together on the path of investigation. However, they are unaware of how close the killer is.

Unwilling to compromise her ambition, Leyla is forced to accept that the investigation cannot proceed independently of Kenan. Doğan, who wants to publicize his ideals, starts threatening Kenan with messages he sends to the press. Hamdi Atılbay is certainly not the last victim. But the presence of Leyla, the prosecutor, puts unexpected obstacles in the path of İdris and Doğan. Doğan's new murder gives clues about the trauma he suffered as a child. Unaware of his split personality, Kenan begins to make excuses for the gaps in his memory. As the number of people Leyla can trust dwindles, the number of victims increases. Turan, who wants to save his son, is tested by turning into an attorney general protecting the killer. Will Kenan comply with Dogan's demands and agree to be the voice of a murderer? Will the enemy living inside Kenan pose a threat to Leyla?

Leyla is shocked when the Doğan she thought was Kenan goes too far. When Kenan regains consciousness, he learns what he has done and tries to make amends. But it is not easy to soften Leyla's anger. As his memory lapses become more frequent, Kenan begins to doubt his sanity. He is not the only one who realizes this. Having failed to kill his last victim, Doğan takes unexpected risks to prevent İrfan from talking. Leyla and Commissioner Refik, whose trust in Kenan is increasingly shaken, play a dangerous game to confirm the killer's connection to Kenan. This time, it is Doğan's turn to fall into the trap. Leyla is not the only one suspicious of Ekrem, whose lies keep piling up. His secretive behavior, which also attracts Tahir's attention, is actually the tip of the iceberg. Doğan and Idris are not the only ones trying to reach Irfan. Doğan now faces new obstacles.

Although Irfan is silenced at the last moment, there will be those who cannot remain silent in the face of some atrocities. Leyla pursues the date September 7, 1995 to uncover the truth behind the murders. Ekrem is unaware that he is caught on Doğan's radar. As the pressure on him increases, the deeper he gets into, the deeper his involvement will get. Moreover, Turan now has bigger worries than his son going to prison. He will have to protect Kenan not only from the police but also from much more dangerous sides. When Ekrem, who is trying to protect his children from the truth, fails to realize the danger that awaits him, the consequences are severe. For the first time, Kenan will feel some of the pains he has suppressed. Leyla is the one who stands by his side in these moments. When they realize how veiled the truth is, Kenan will resort to an unusual way to get the answers they are looking for.

Caught in the middle of a fierce battle between those who want to cover up the fire at the orphanage and those who want to expose it, Leyla and Kenan realize that the enemy is not afraid of them. The past they have carved out now threatens their lives. Moreover, an unexpected emotional confession will make their work much more difficult. As Turan tries to keep his son away from the field of fire, Nevin learns frightening information about Kenan's mental disorder. How far will Doğan go as he tries to take back what belongs to him? Unable to cope with Dogan's impulsiveness, Idris is forced to resort to harsh methods. But Ekrem is now Doğan's open target.

Kenan, who is building an increasingly close relationship with Leyla's family, is unaware that he is creating an opportunity for Doğan. Having once again lost Ekrem, whom he blames for the orphanage fire, Doğan finds a different way to torture Leyla's father. Leyla, who wholeheartedly believes in Ekrem's kindness, gets one step closer to learning about her family's past. But the closer she gets to the truth, the more people try to block her path. Struggling with his guilty conscience, Tahir is ready to do whatever he can to protect his family. Nevin, who learns that Kenan's condition is more serious than they thought, decides to act independently from Turan. After everything that has happened to them, Kenan can no longer hide his love for Leyla. Leyla, on the other hand, finds it difficult to open up to Kenan about the love she has accepted within herself. The suppressed intensity of emotion leads the two to inevitable confessions.

After a disaster at the courthouse, Leyla takes a step away from the truth once again. However, a clue found after the incident determines the new target of the investigation. Nevin, who reveals the truth to the wrong person, begins to think that he has no choice but to start accepting Doğan as his son. Turan, who, unlike his wife, cannot accept Doğan, has a striking confrontation with Idris. Tired of living in fear, Ekrem decides to take matters into his own hands. Doğan, who has been hunting his targets until now, will be the prey this time. The lies Şahinde and Ekrem tell to hide the truth lead Tahir down a dark path. The turmoil caused by Nuray's jealousy reveals Tahir's hopes for Yasemin. Murat is the one who rushes to Yasemin's support in her most difficult moment. While Leyla prepares for big changes to stay away from Kenan, Kenan sacrifices the most important part of his life to stay close to her.

For the first time, Leyla stops resisting her love for Kenan. The couple thinks they will enjoy their love. Until their fate takes a dark turn... While Idris struggles to survive, he learns about the suffering of Nevin Doğan. Doğan, who cannot reach Idris, appears before his family with his true self for the first time in years. This time it is Turan's turn to confront Doğan. Kenan and Leyla's love affair scares Turan as well as Doğan. Tahir's new job takes him on an unexpected path. The clue Ekrem follows leads him to a great discovery. A new face who managed to escape his terrible fate adds a different dimension to the investigation. As the truth about the orphanage fire begins to emerge rapidly, Doğan is the person who enables the investigation to take a big step forward. This new incident affects both Kenan and Leyla; It will shake the whole of Turkey and deeply affect the course of everything.

Having lost her father to a murder, Leyla's nightmare has come true. Even as she experiences the deepest pain of her life, she does not listen to anyone's advice and goes after Ekrem's killers. Kenan, who does his best for Leyla, is unaware of what is going through his family's mind. When all the evidence points to Doğan as Ekrem's killer, Idris aligns himself with Turan and Nevin for the first time. Determined to prove that he did not kill Ekrem, Doğan finds the only person he trusts in life against him. Nevin and Turan, who can no longer bear the guilt they feel in front of Leyla, come to the brink of a big decision. While Şahinde mourns her husband, Nuray makes a move to gain the upper hand at home. Tahir, who becomes emotional after losing his father, shows up at Yasemin's door uninvited. However, he will not be the only one knocking on Yasemin's door at a bad time. When Elif is trapped again, she clings to life with the hope she gets from Leyla.
