Hugo is appointed a job in which he has to make peace between two planets before they go to war. He is given a galactic communicator that looks like a cellphone. Due to Chris' curiosity, he takes the communicator and loses it when he crashes into Mark and the devices get mixed up. Mark keeps getting the calls meant for Hugo and insults Zubin. The two planets go to war on Earth. Soon after the space ships arrive, Chris and Cathy get back the communicator and make peace between the planets.
