However, when Zim misinterprets the 8 billion served sign and thinks that the individuals in charge of the company are the leaders of the planet, he becomes dedicated to his job in hopes of being promoted to Lord of All Humans. However, thanks to the alignment of the planets, Zim is about to go through some uncontrollable changes that could jeopardize his mission; which Dib is looking to exploit, though both Zim and Dib find their situations to go much different than they anticipated.
