Hassan has nothing else in the world other than his wonderful parrot. When the rich neighbour's dog threatens the bird, Hassan defends it so vigorously that the dog is soon lying dead before him. From then on, Hassan must serve the rich man in the dog's place; this is the judge's sentence after the rich man has "bought" the verdict. But the hour comes when Hassan takes his revenge for this injustice.

This Brechtian children's film draws on motifs from an Uyghur fairy tale.
