Welcome to Holiday High, a magical school that exists for those who believe in holidays most, entrusted to safe-keep the wonder. When legacy enrollee Eve December is surprisingly placed into the Halls of Halloween, all her Christmas dreams disappear into a thick haunted fog. With only one chance to earn her way back to Campus Christmas, Eve must lead a misfit crew of ghouls, monsters, witches, and costume keepers to reignite a forgotten All Hallows' Eve tradition of magic, music, and song... just in time to find that there's more than one place our hearts can belong.
