When the power fails in Gumnut Gorge, the Numtums find themselves with no termite treats, no Super Numtum episode and no Gumnut Express. To restart the power they have to find the five keys that open the five locks on the windmill. While they are looking Little Sandy plans to create her own power. Meanwhile, on the Adventures of Super Numtum show, Super Numtum and Fluffy McTuffy are locked in a dungeon, when the power goes off, leaving them into darkness. They need to work together to open the five locks to the dungeon door.
