In an abandoned lighthouse miles from shore, the Dark Master meets with his henchmen to plan the final battle, desperate to regain ownership of his Hopewell Indian copper box and the mysterious item within. Young Darach is shocked to find that his beloved grandmother Rosemary, a powerful witch, has turned traitor--betraying her family by joining the Dark Master on a mission to destroy all plant life on Earth. Frustatingly, Rubus is now imprisoned--thanks to the workings of the Dark Master--and can no longer help Darach. Imprisoned in his basement bedroom, Darach is subjected to mind-altering spells in an attempt by his abusive father and weird step-mother to force him into revealing the copper box's hiding place. Assisted by a centuries-old teenage boy vampire, The Queen Oak tree of the forest, and an army of elves, Darach confronts the Dark Master in an isolated cemetery for a final, winner-takes-all battle.
