The ancient Egyptians believed in life after death. Contradictions, however, existed side by side in their belief regarding the afterworld. They thought that the dead lived on in the tomb. At the same time they thought of the dead as having gone to a blessed afterworld in some far-distant place. Such inconsistency did not disturb the Egyptians: they provided for both. In no other civilization have such elaborate preparations for the afterlife been made in the preservation of the dead.
In 1926, a group of archeologists stumble upon a tomb at Hamunaptra. Inside this tomb the group finds the body of Imhotep, Pharoah Seti's priest and one-time lover of Seti's mistress. However, when the group accidentally brings Imhotep back to life, the results are fatal.
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 Anck-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.
