Nabi is an Afghan migrant worker in Iran who, after 25 years of working in a tower as a janitor, realizes that he has to leave the next day. He must work in the tower for the last day before leaving and then leave as if he never existed because no law protects him. Like many people whose names will never be recorded in history. They are never seen and always live like shadows and are fading away. The people you see when you get close to them are full of pride, passion for life, and understanding, while having a sense of fear and humiliation.
