This work is a free adaptation of the story The Big Bang from the Dark Half of the Moon series by Houshang Golshiri. A lonely, ambulatory old man named Fazlollah gives meaning to his life with small pleasures and spends his daily life talking to his absent wife. Those around him pay no attention to him and his communication is limited to daily phone calls. But one night, the sound of the neighbor's setar, one of his pleasures, goes silent.
