One day, while goofing around in a museum rocket display, our hero Max, somehow managed to launch himself into space. After a giddy ride, he crashed into the home of Kendra, a Deaf teenager, and inhabitant of Deaf Planet. Max is at first confused by the sign language used on the planet, but is helped by his ship’s WILMA, a robot capable of interpreting every language in the universe. Kendra promises to get Max home with the help of the many wise and eccentric inhabitants of Deaf Planet.
