An out-of-this-world comedy cast stars in this spaced-out futuristic family comedy. Welcome to Betaville, the world’s most exclusive summer camp, where the world’s leaders send their children. They are the sons and daughters of presidents and kings, with supervisors to care for them and an army to protect them. Meanwhile, in outer space, Planet Z is threatened by the evil forces of Planet 38. Planet Z’s president XM (Tim Kazurinsky) launches a secret plan to trick Planet 38 into attacking Earth instead. A peace-loving emissary from Planet Z recruits the children of Betaville to warn the President (John Astin) about XM’s secret plan.
Ao término do primeiro ano da faculdade, Jim (Jason Biggs), Oz (Chris Klein), Kevin (Thomas Ian Nicholas), Stifler (Seann William Scott) e Finch (Eddie Kaye Thomas) mais uma vez se reencontram. Mas agora Nadia (Shannon Elizabeth) está prestes a vir visitar Jim, que ainda não se sente preparado sexualmente para encontrá-la e receberá a ajuda dos amigos.
