Nasrin and Adib’s collaboration wavers between logic and emotion, while Bahram tries to steer the case in his favor; however, the arrival of an unknown person turns everything around.

After being away from Tehran for some time, Bahman Moghaddam turns himself in to the police. Even in Nasrin’s presence during the interrogations, Bahman remains silent and continues to deny everything. In the end, Adib’s investigation reaches a critical stage, and the case takes a new turn.

Nasrin is caught in a fierce struggle between her maternal instincts and the law. Adib and Kamrani discover a new lead that could change everything. But the further they go, the hidden secrets of the case begin to reveal new faces...

The discovery of Saleh’s body sets off a chain of tension and suspicion. Nasrin fights with all her strength to defend Mahyar in court, while the shadow of doubt around Bahman still looms large. Yet just when everyone expects peace, Mahyar’s shocking final act changes the course of the case—and everyone’s fate.

With the discovery of the murder weapon and the start of the second trial, everything reaches a critical point. However, in the end, Mahyar makes an unexpected decision that completely changes the course of the case and his relationship with his mother.

Nasrin fights with all her strength to make the truth heard, while Adib stands by her, striving to build a bridge between the law and his conscience.

Nasrin tries to win the victim’s family’s consent and prevent Mahyar’s execution, but she faces strong resistance from Nahid, Taban’s mother. In the end, however, everyone’s persistence softens Nahid, and she, too, agrees to forgive. But the arrival of an unknown figure throws everything into turmoil.

Nasrin, in her effort to uncover the truth behind Mahyar’s case, finds herself confronted with the mysterious death of Bahman’s mother and Bahman’s own disappearance—events that upend the course of the investigation and open a small window of hope for Mahyar’s release. Yet just as calm begins to settle in, the hidden presence of an unknown figure casts a shadow of uncertainty and tension over what lies ahead.

After Mahyar’s release, emotional tensions and conflicts between him, Nasrin, Khosrow, and Bahram intensify, and under growing psychological pressure, Mahyar leaves home. His sudden disappearance and the fact that his phone is switched off push the family’s worries to their peak. At the height of this confusion, the discovery of an unidentified body—whose identity, after investigation, shocks everyone—drives the story toward a dark and complicated path.

Adib moves forward step by step to identify the suspects by persistently following leads and piecing together clues. Meanwhile, the relationship between Khosrow and Nasrin, under the strain of worries, misunderstandings, and Mahyar’s situation, grows increasingly distant and tense. In the end, with the discovery of the identity of one of the suspects, the case not only remains open, but the story enters a new challenge and a more complex mystery.

Adib and Kamrani discover a new lead related to Farhad, and the focus of the case shifts to his family and close associates. Despite the warnings, Nasrin personally gets involved and, with Khosro’s help, ventures into neighborhoods and hangouts to reach a clue as quickly as possible. At the same time, the pursuit of Farhad’s son begins, and the signs point to getting closer to the hideout and unraveling the case—until…

With the discovery of Farhad’s body in an abandoned cowshed, the police reach a new lead in a complex murder case. By piecing the evidence together, Adib and Nasrin uncover traces of an old revenge and its connection to past closed cases. In the end, the main suspect gradually emerges from the shadows, and the story enters a dangerous and decisive phase.

Adib is removed from the case before he has come anywhere close to the truth, as pressure from the system pushes him into a dead end. Ismail’s death and Nasrin’s intense emotional turmoil add a bitter, deeply emotional layer to the story, highlighting its human dimensions. The final confrontation between Adib and Bahram reveals that the case is not only unresolved, but has in fact entered a more dangerous and complex phase.

The interrogation of Taha and Bahram reaches a dead end, pushing Adib further away from the truth. Nasrin's desperation forces Adib to cooperate with Khosrow in the search for Aqil— a perilous alliance that, instead of resolving the issue, leads to a disastrous outcome.

After Khosrow gets killed, Aghil contacts Nasrin and threatens her. Meanwhile, Adib, who has returned to work, resumes the case. The search for Aghil continues and new leads are revealed.

The search for Aghil continues as new clues bring Adib and the crime team closer than ever to the main suspect; but this shows that the case is not only not over, but has entered a new phase.
