Takhté siah – Blackboards (2000)

Directed by Samira Makhmalbaf. A group of male teachers crosses the mountainous paths of remote Iranian Kurdish region. The men wander from village to village in search of students, carrying large blackboards on their backs – used as shelter, camouflage, and shields instead of for teaching purposes. One by one the men venture away from the group in search of students to teach. Along their way they face other hardships and obstacles, including enemy helicopters and gunfire.
