Years after the fall of Saddam Hussein, Kurdish singer Mamo (Ismail Ghaffari) intends to sing at a concert in Iraq. However, he lives in Iran and must travel to cross the border. He calls his children to accompany him -- and serve as back-up musicians -- and they begin an arduous journey in an old bus. They stop by a village to pick up a female singer, and must face harsh Iranian authorities at the border. However, a mysterious woman named Niwemang (Golshifteh Farahani) comes to their aid.
