King Roland of the planet Druidia is trying to marry his daughter Princess Vespa (Daphne Zuniga) to Prince Valium, but Vespa is kidnapped by the evil race of the Spaceballs. The Spaceballs ask Roland a tremendous ransom: all the air of Druidia (you see, the air of Spaceball had serious pollution problems…). The King decides to offer a generous amount of money to a space rogue, Lone Starr, to persuade him to save Vespa. What follows is the parody of a _LOT_ of famous SF movies.

The Empire is more than halfway through construction of a new Death Star - almost twice as big, but more than twice as powerful. When completed, it will spell certain doom for Luke Skywalker and the Rebels. Han Solo is a prisoner of crime lord Jabba the Hutt, and Princess Leia soon finds herself in the gangster’s hands. Luke Skywalker, aided by C-3PO and R2-D2, makes his way into Jabba’s palace, hoping to secure his friends’ freedom. But the Hutt has no intention of doing so and tries to kill them all. After escaping from Jabba and the sands of Tatooine, they regroup with the Rebel fleet, which is massing for an attack against the new satellite battle station at Endor. Lando Calrissian is pressed into action to lead the Rebel fighter attack, while Han is put in charge of a group of soldiers to take out the shield generator protecting the Death Star. Luke, however, surrenders to Vader’s soldiers on Endor, and is taken in front of Vader’s boss - the Galactic Emperor - on the Death Star for final corruption to the Dark Side of the Force. The fleet of Imperial Star Destroyers ambushes the Rebels, cutting them off. Worse, the new Death Star begins turning its giant laser on the Rebel carriers. It appears that nothing will stop the Empire’s triumph - unless things start to change quickly…

In ancient Egypt, high priest Imhotep started a forbidden relationship with Anck Su Namun, Pharaoh Seti’s Mistress. When Seti finds out about what’s going on, Imhotep and his loved one stab him, but can’t escape the trustworthy guards: Anck Su Namnun chooses to commit suicide while Imhotep is bestowed with the Hom-Dai, the most feared curse of all: He is mummified alive in Hamunaptra, the city of the Dead. More than thirty-six centuries later, in 1923, to be exact, adventurer Rick leads Egyptologist Evelyn and her brother Johnathan to mysterious Hamunaptra. While Johnathan is keen on finding the legendary Egyptian treasures, Evelyn wants to search for the Book of the Living, which would clarify a lot in historical knowledge about the ancient Egyptians. Unfortunately, they and a rivaling group of careless American adventurers free Imhotep’s mummy from his eternal prison. Now, with the ancient and quite agile high priest on the loose, the adventurers and scientists face not only a dangerous enemy, but also a massive threat to today’s world: Imhotep wants to bring Ankh-su-namun back to life by using Evelyn’s body, but he also wants to rid the world of the disbelieving crowd of democracy-supporters to be able to enforce his tyrannic dictatorship.
