Willow has inherited not only her grandmother's entire fortune but also a secret book of magic. It turns out she is descended from an entire line of witches. Using the book, she summons the sorcerer Grimoo, who is to help her awaken her fire powers. Everything would be fine, except that her father plans to sell the forest from which all of Willow's magic originates. She doesn't have much time left to awaken her full magic power and, together with three other witches, save the existence of the ancient, enchanted forest.
