Lia and her family are leprechauns-which means they all wear green, to hide from the humans who might otherwise steal their gold or demand they grant wishes. Still, Lia wishes she could try on some of the other beautiful colors she sees in the forest. When she gets the chance, Lia dares to swap her usual green outfit for a beautiful purple fairy dress. But when she meets a human girl who needs her help, Lia comes to appreciate who she is and the magic she holds inside.
