Asha, a sharp-witted idealist, makes a wish so powerful that it is answered by a cosmic force – a little ball of boundless energy called Star. Together, Asha and Star confront a most formidable foe - the ruler of Rosas, King Magnifico - to save her community and prove that when the will of one courageous human connects with the magic of the stars, wondrous things can happen.
