The land of Mirrios is terrorised by an evil necromancer who holds the land's guardian, the silver-horned unicorn, Mirabelle, captive. Meanwhile, in Melbourne, Australia, a young girl, Helen, is being terrorised by school bullies. Through a magic door, Helen escapes into Mirrios where she becomes caught up in an adventure that helps her discover her own inner strength. There, she finds that a stone she once found in a creek near her home is really a message from Mirabelle. Helen, or Elena as she is called in Mirrios, meets a little gnome called Pea and his friend Cat, as well as an elf, Nancha, and a boy, Kam. Together, they set out on a quest to save Mirabelle. But, a Melbourne schoolgirl, an elf child, a young boy, a little gnome and a cat - how can any of them defeat the powerful necromancer and his evil goblins? How can they break into his mountain fortress and free Mirabelle from her chains?
