In the village of Le-jeute, all is not well. Over-shadowed by the dark and mysterious factory-city known as Balthus, the inhabitants of the peaceful little village are lured into a life of servitude with the promise of the pleasures that await them. But when the workers realize the truth, it is too late as they are unable to leave the forsaken factory. In an effort to organize a resistance movement, a small group of fearless workers prepare to wage an attack on the evil factory owner Morlock. Their secret weapon, a robot named Klaattu, sits idle as Eud and Alphonse attempt to escape and warn the rest of the villagers. But Alphonse is lost in the attempt while Eud escapes, only to be found by Alphonse's sister, the beautiful Tia. Their peace is soon shattered as Morlock comes looking for Eud, and eventually captures him and Tia together. While Eud is thrown in a dungeon, Tia is subjected to Morlock's sexual appetite, only to find out that her brother is dead. Can Eud and the other resistance workers fight to bring down the evil Morlock? Will Tia be subjected to Morlock's sadistic pleasures for the rest of her life? Find out in this wonderfully drawn and classically animated adventure in a fantasy world of Gilliamesque creations and gothic scenery.
