In a distant galaxy, planet Spaceball has depleted its air supply, leaving its citizens reliant on a product called "Perri-Air." In desperation, Spaceball's leader President Skroob orders the evil Dark Helmet to kidnap Princess Vespa of oxygen-rich Druidia and hold her hostage in exchange for air. But help arrives for the Princess in the form of renegade space pilot Lone Starr and his half-man, half-dog partner, Barf.
