The song of sparrows (2008)

When an ostrich-rancher focuses on replacing his daughter's hearing aid, which breaks right before crucial exams, everything changes for a struggling rural family in Iran. Karim motorbikes into a world alien to him - incredibly hectic Tehran, where sudden opportunities for independence, thrill and challenge him. But his honor and honesty, plus traditional authority over his inventive clan, are tested, as he stumbles among vast cultural and economic gaps between his village nestled in the desert, and a throbbing international metropolis.
