Apparently many people don't want Hamed to prove the innocence of Fereshteh. Upon the first witness coming forward, a dead body has to be dealt with by Hamed and nothing is accidental.
How come Mahtab started representing the Ashiris? When Emad and Amir Ashiri reopen old wounds, a few months later Hamed and Mahtab find themselves in the middle of a fire they did not start. Nothing is a coincidence.
Hamed takes Mania to court. Mahtab's feelings about Fereshteh and Hamed's relationship get complicated. After the incident in the courtroom, Hamed doubts everything.
Finally there remained no choice. Mahtab remembers what happened after the murder of Amir Ashiri that led her to this situation. Meanwhile it's apparent that Hamed and Navid hold grudges against each other and will confront one another.
Hamed suspects something is wrong with the defense of Fereshte's previous lawyer. Moshfegh knows there's no evidence for that. Meanwhile, Rasouli, the previous lawyer, makes a rash decision with consequences.
