Melody teaches music at a centre for cancerous children. The thirty children are having a party at the end of autumn and ask Melody to compose a piece using the sounds of thirty different birds. She goes to her home village to record the birdsong and is helped by the mute caretaker of the family home, Mango. When they find just 20 birds, Mango makes Melody understand that only the old village singer knows where the other birds are, but bird hunters have forced him out of the village. Melody sets out to find both him and the missing birds.
