Tuba works daily at a grueling textile factory in Iran, returning home every night to deal with the rest of her problematic family, which includes: a pregnant daughter whose husband beats her regularly; a teenage son, who's been getting into trouble due to his burgeoning career in radical politics; and an older son who goes to great lengths--such as attempting to sell the family's meager house--in order to get an engineering job in Japan as a means of getting out of Iran.
