Context: In Egypt, circa 1290 BC, high priest Imhotep engages in an affair with Anck-su-Namun, the mistress of Pharaoh Seti, despite strict rules that other men are forbidden to touch her. When the Pharaoh discovers their tryst, Imhotep and Anck-su-Namun murder the monarch. Imhotep is dragged away by his priests before the Pharaoh's guards can discover his involvement; Anck-su-Namun then kills herself, intending for Imhotep to resurrect her. After Anck-su-Namun's burial, Imhotep breaks into her crypt and steals her corpse. He and his priests flee across the desert to Hamunaptra, the City of the Dead, where they begin the resurrection ceremony. However, they are caught by Seti's guards before the ritual could be completed, and Anck-su-Namun's soul is sent back to the Underworld. For their sacrilege, Imhotep's priests are mummified alive, and Imhotep himself is forced to endure the curse of Hom Dai: his tongue is cut out and he is buried alive with a swarm of flesh-eating scarabs. The ritual curses him to become an immortal walking plague if he were ever to be resurrected. He is buried under high security, sealed away in a sarcophagus below a statue of the Egyptian god Anubis, and kept under strict surveillance throughout the ages by the Medjai, descendants of Seti's palace guards. If Imhotep were ever to be released, the powers that made him immortal would allow him to unleash a wave of destruction and death upon the Earth.In 1923, soldiers from the French Foreign Legion, led by American Rick O'Connell, make a final stand at Hamunaptra against an overwhelming force of Medjai warriors. The soldiers are massacred and O'Connell makes a final retreat inside the city, only to be cornered by a group of Medjai. However, they flee when Imhotep's evil presence manifests itself, leaving him to die in the desert.In 1926, Cairo librarian and aspiring Egyptologist, Evelyn Carnahan is presented with an intricate box and map by her bumbling brother Jonathan, who says he found it in Thebes. The map seems to point the way to the lost city of Hamunaptra, where all of the wealth of Egypt was supposedly stored; however, the museum curator, Dr. Bey, dismisses Hamunaptra as a myth, and accidentally damages the map. Jonathan reveals he actually stole it from an American (revealed to be O'Connell), who is currently in prison, and may be able to tell more about Hamunaptra. Rick tells them that he knows the location of the city from his days in the Foreign Legion. He makes a deal with Evelyn to reveal the location of Hamunaptra, in exchange for Evelyn saving Rick from being hanged. Evelyn successfully negotiates his release from the prison warden by offering him 25% of the found treasure; however, the warden insist on coming along in order to protect his investment. They board a ship to start their expedition to the city, where they encounter a band of American treasure hunters led by the famed Egyptologist Dr. Allen Chamberlain, and guided by Beni Gabor, a cowardly former Legion soldier who served with Rick and also knows the location of the lost city.During the journey, the boat is invaded by Medjai soldiers who are looking for Evelyn's box and the map. The expedition manages to fight them off, but the map is lost and the boat goes up in flames, forcing the entire party to go ashore. Rick, Evelyn and Jonathan are separated from the other treasure hunters and procure camels at a nearby market. Since Rick knows the way to the city, they arrive at Hamunaptra at the same time as the other party, but due to tensions between the two groups, they start exploring the city in separate locations. The Americans discover a chest between the legs of the statue of Anubis. They have it opened by several of their carriers, but the chest is booby-trapped and the carriers die from an acid spray. In the meanwhile, Evelyn is looking for the Book of Amun-Ra, a solid gold book supposedly capable of taking life away. Her team discovers a tomb buried directly below the statue of Anubis
