The Night Between follows investigator Gisoo Radmanesh and psychologist Marco Conti as they examine the life of Arsham Nikpey, a man whose name has suddenly become the center of a tragic event. Instead of focusing only on the crime, they search the years that came before it—the unnoticed silences, small withdrawals, and moments when a person begins to stand just outside the circle of others. As media pressure rises and public judgment forms quickly, the investigation turns into a deeper question about responsibility, loneliness, and the fragile boundary between an ordinary life and an irreversible decision.
