Joe Young (Parker) is a devout Mormon living in L.A. trying to raise enough money to go back to Utah and marry his girlfriend Lisa (Robyn Lynne Raab). Joe is spreading the word about the church of Latter Day Saints one day when he's confronted by two burly bodyguards.

A scuffle breaks out, and Joe's martial arts skills impress Maxxx Orbison (Michael Dean Jacobs), who directs pornographic movies. Maxxx offers Joe $20,000 to star in his latest skin flick as X-rated superhero Captain Orgazmo. While Joe is wary, he agrees under the condition that a body double is used during the sex scenes. Ben Chapleski (Dian Bachar), who plays the good captain's sidekick Choda-Boy, has invented a real-life version of Orgazmo's secret weapon, a gun that stuns people with spasms of sexual ecstasy.

When Joe and Ben learn that Maxxx is involved in organized crime, they leap into action to see that justice is served. Meanwhile, their film becomes a surprise crossover success, which means that Joe has a lot of explaining to do to Lisa. Trey Parker cast Orgazmo with a number of real-life adult film stars, including Ron Jeremy, Julie Ashton, and Chasey Lain.
