Rang-e khoda / The Color of Paradise - by Majid Majidi (1999)

Mohammad, a boy at Tehran's institute for the blind, waits for his dad to pick him up for summer vacation. While waiting, he realizes a baby bird has fallen from its nest: he chases away a cat, finds the bird, climbs a tree, and puts it back. His father finally comes and takes him to their village where his sisters and granny await. The lad is a loving student of nature and longs for village life with his family, but his father is ashamed of him, wanting to farm the boy out to clear the way for marriage to a woman who knows nothing of this son. Over granny's objections, dad apprentices Mohammad far from home to a blind carpenter. Can anything bring father and son together?
