This sci-fi flick shows that even the littlest ones can save the world. Problems surface when Planet Z's leader (Tim Kazurinsky), under threats of invasion by Planet 38's menacing residents, tries to deflect the negative attention by foisting the invaders onto Earth. Good thing one of Planet's Z's denizens is kind enough to warn the president (John Astin) of the impending crisis. To do so, he must enlist the help of Camp Betaville's attendees.
