Comical chaos erupts when milquetoast astronaut Peter Mattemore (Jerry Lewis) and his bride-of-convenience and fellow astronaut (the government forced them to marry to avoid scandal) Eileen Forbes (Connie Stevens) are sent to a lunar space station, which they will share with a Russian couple, to monitor the weather and replace their two predecessors, both of whom have gone bonkers.
