Sam can't believe it. His own grandfather is a real magician—and not just magic tricks, REAL MAGIC!! Now the old man is summoning some strange beings from another world, and he's warned Sam: There must be complete silence. The room begins to glow...it swirls with color...the spell is working... "Oh, wow!" yells Sam, forgetting. Instantly, there's a loud popping sound, and his grandfather disappears! He's been zapped into that other world—and it's up to Sam to get him back. But can he? Can he really reverse the spell?
