The father and mother of four brothers are in the bombing of a municipality; there are no traces to be found of their bodies. Their four sons Hadi (a film director), Jafar (a physician), Hassan (an engineer) and Jalal (a trader) go back to the the city of their birth to see their demolished home. The father appears intermittently before each of the brothers telling their mother is not well. The brothers begin an extensive search for their father and mother. They ultimately realize their parents have lived through the bombing.
