December 1

Ali, the youngest child of the Poladi family, has returned to his father's house after a few years. His older brother Omid was a politician and was arrested by the government and of course with the cooperation of his mother. Omid dies in prison for unknown reasons. The time is now, 1 Azar 1401. Ali is preparing for an interview with a foreign media outlet due to the proximity of Omid's anniversary, which is scheduled to be broadcast in a few weeks. His mother is worried about this, but Ali ignores it. Ali does the interview, but after a few hours the interview is broadcast on various networks and media outlets. He doesn't know what to do and is very worried about this. In the meantime, he hears his mother's voice from the other side of the wall saying, "I opened the door, come upstairs and get ready." Ali has lost consciousness. Then he goes to his mother's room and starts to strangle her and finally kills her. Finally, he is about to leave the house. Suddenly, he sees his friends with cakes in their hands, all of them shouting, "Happy birthday."
