Asha lives in the foothills of the Himalayas. Money is tight and she misses her papa who works in the city. When he suddenly stops sending his wages, a ruthless moneylender ransacks their home and her mother talks of leaving.

From her den in the mango tree, Asha makes a pact with her best friend, Jeevan, to find her father and make things right. But the journey is dangerous: they must cross the world's highest mountains and face hunger, tiredness - even snow leopards.

And yet, Asha has the unshakeable sense that the spirit bird of her grandmother - her nanijee - will be watching over her.
