The celebrated Iranian photographer, Nasrollah Kasraian and his wife, anthropologist Ziba Arshi, have documented many unique populations living within the borders of Iran. This film provides a fascinating look at the Turkmans of Iran, who live in small villages northeast of Teheran, near the Afghanistan border. It examines how Turkman society has changed over several years. Devil on the Roof captures varied aspects of their traditional culture. It shows how shamans treat physical and mental illnesses with music, sticks and swords. It depicts the women's roles - raising children, working in the rice fields and weaving magnificent rugs and clothing. Four years after the initial filming, the filmmakers return to the Turkman villages where they find radical changes have occurred.
