Description
In 1893, a young Arab girl arrives in Galveston, Texas as a stowaway on a ship with her mother. Her mother dons a magical bracelet, and lies helplessly on the boat as a malevolent jinn murders everyone on board. The girl manages to flee the scene, taking with her a brass lamp and the bracelet.
Many years later, three criminals—two men and a woman—burglarize a mansion owned by the now-elderly woman. When confronted by the criminals, the woman attempts to fight them, but one of the men, Harley, kills her with a hatchet. Harley finds the brass lamp in a lock box. Unbeknownst to him, the genie is released from inside and possesses the old woman's corpse, violently murdering the three burglars.
After surveying the crime scene, an officer sends the evidence, including the lamp and bracelet, for display at the Houston Museum of Natural Science. From inside the lamp, the genie observes the museum's curator, Dr. Bressling, cataloguing the newly arrived artifacts. Dr. Bressling later determines the brass lamp dates back to 3500 BC. The museum archaeologist, is visited by his teenage daughter, Alex, who surreptitiously tries on the bracelet. She and her father subsequently get into an argument about his demanding work schedule, during which Alex tells him she wishes he would die. Afterward, Alex finds herself unable to remove the bracelet from her wrist, and notices a red jewel on the lamp glowing in conjunction with the bracelet.
The next day, Alex and her classmates take a field trip to the museum. There, Dr. Wallace greets Alex's teacher, Eve, whom he is dating. Alex secretly enters her father's office to further inspect the lamp, during which the jinn possesses her. After, Alex convinces her friends—couples Babs and Ross, and Gwen and Terry—to go on an "outing" to secretly spend the night at the museum. Alex's abusive ex-boyfriend, Mike, learns of the outing and plans to sabotage it. Meanwhile, the genie levitates Dr. Bressling's body and decapitates him with a ceiling fan in his office.
That night at the museum, Alex and her boyfriend Ted are met by Babs, Ross, Gwen, and Terry. The group enter the museum, where Alex leads them to the basement where they plan to stay the night and elude the building's security guards. After Babs spills beer on her pants, she and Ross go to the specimen room to use the shower. The jinn disembowels Ross before unleashing jars of poisonous snakes that kill Babs. Terry finds their bodies shortly after, and is also killed by the snakes.
Meanwhile, Mike and his friend, Tony, break into the museum basement, and don masks they find in an artifact storage area. Mike and Tony stumble upon Gwen in one of the rooms and attack her. Mike rapes Gwen while Tony watches, but the jinn interrupts, killing all three of them. Alex and Ted hear their screams, and rush to the scene. The jinn possesses a mummy, which it uses to kill Ted. It also uses a snakeskin to murder an opera-singing security guard who works in the museum. Meanwhile, while Dr. Wallace and Eve are having a dinner date, they realize that Alex lied about her plans that night, and quickly rush to the museum.
Dr. Wallace and Eve find Alex fleeing through the museum, chased by the jinn, which has revealed its true monstrous form. The jinn tells Alex she is to be the new keeper of the lamp. Pursued by the jinn, the three manage to flee outside, but the jinn kills Dr. Wallace, which neither Alex nor Eve witness. The jinn then animates Dr. Wallace's corpse in an attempt to trick them. Realizing she must destroy the lamp to banish the jinn, Alex throws it into an incinerator inside the museum.
