After realizing that their beloved boob tube is gone, couch potatoes Beavis and Butt-head (both voiced by creator Mike Judge) set off on a cross-country expedition that takes them from Las Vegas to the nation's capital. Along the way, they're mistaken for hit men and get caught up in a weapons-smuggling conspiracy as a gaggle of mobsters and lawmen shadow the two morons. Celebrity voices include Cloris Leachman, Robert Stack and David Letterman.
