In this magical family adventure, Mindy adopts Angel, a high-spirited pony that—according to legend—will lead its owner to gold hidden in the nearby mountains. When Angel is kidnapped by a mad treasure hunter, Mindy and her school friends head into the hills to rescue the pony and hunt for the lost gold. But Mindy meets a mountain man that warns her the treasure is part of an ancient curse—if they remove the gold, they’ll destroy the beautiful forest.
