For more than three decades, aging Iranian Mohamad Sardari (Zadour Bonyadi) has worked as a crossing guard at a desolate train station. Through the years, Mohamad has done little to stifle the loneliness and boredom inherent in the job. Meanwhile, back at his family home, life is similarly uneventful: Mohamad's wife passes the time sewing night and day, especially since the couple's son left to join the army. As time passes, Mohamad mechanically continues to do his duty.
