Passing Through the Mist (1990)

Rashid Bakhti [Khosro Shakibai] is a school teacher who lives in a village on the outskirts of Tehran with his wife Iran [Mahnaz Afzali] and son. With difficulty he is able to build a house on a hill but he soon realizes Iran is about to die from a kidney disease. Because of his bad financial situation, nothing he does for Iran is of any use until the mother of one of his apparently undisciplined students goes to the hospital without the Rashid's knowledge and donates one the student's kidneys to Iran.
