Leon, a high school basketball star, and his younger sister Leyla, who often feels overshadowed by her brother's success, find themselves on a magical adventure at The House of Grinwoll, an enchanted ice cream parlor on Mackinac Island. Accompanied by a group of misfit teens and the wisdom of the Seven Grandfather Teachings, they must navigate fantastical Scoop Loops-challenges within magical ice cream worlds that test their character-and confront their own failings to restore balance to the island.
