In ancient Egypt, Princess Ahmanet is in line to rule over the pharaoh's kingdom, until the pharaoh sires a son. Knowing that her place to rule has been taken, she makes a deal with the deity Set and is given demonic powers through a ceremonial dagger. She murders her family and attempts to set the deity free, but is caught and mummified alive by Egyptian priests for her crimes. Her sarcophagus is then entombed in a region far away so she can never escape.
In present-day London, construction workers discover the tomb of a crusader knight who was buried with an Egyptian ruby, and Dr. Henry Jekyll takes over the operation. In Iraq, former U.S. Army Staff Sergeant Nick Morton and Corporal Chris Vail discover the tomb of Princess Ahmanet, unknowingly bringing Ahmanet back to life. British archaeologist, Jenny Halsey, and the soldiers fly with Ahmanet's sarcophagus to Britain.
During the flight, Chris is possessed by Ahmanet through a spider bite, and he attacks the others, only to be killed by Nick. A large flock of crows attacks the plane and is sucked into the engines. The plane crashes, killing the crew except for Jenny, who escapes with a parachute Nick gives her.
Nick returns to life in a morgue. Chris's ghost appears and tells him he has been cursed by Ahmanet, who seeks to use him as a vessel for Set. Ahmanet's mummy escapes from the sarcophagus and begins feeding on people to regenerate her body, turning them into zombies. She recovers the Dagger of Set and attempts to stab Nick before realizing that the ruby is not attached to it. She and her army chase after Nick and Jenny until soldiers appear and subdue her.
Jekyll explains that Jenny is an agent of Prodigium, a secret society dedicated to hunting supernatural threats. Nick and Jenny discover that Jekyll intends to allow Set to possess Nick's body completely, believing that this will render Set vulnerable. Jekyll transforms into Eddie Hyde. Nick stops him with a serum that Jekyll invented for this purpose, allowing Nick and Jenny to escape. Ahmanet finds them, regains the dagger, summons many crusader zombies, and creates a large sandstorm in London. The crusader zombies kill the Prodigium soldiers and scientists and Ahmanet recovers the ruby, combining it with the dagger in order to free Set.
Guided by Chris's ghost, Nick and Jenny flee into the London Underground, where Ahmanet's zombies attack them. Ahmanet captures Jenny and drowns her. When Nick is brought to Ahmanet, he sees Jenny's body, and the zombies turn to dust. Nick is injured when he tries to attack Ahmanet and lets her embrace him as a ruse to steal the dagger and shatter the ruby. He strikes the pommel of the dagger against the floor, cracking the ruby, but Ahmanet reminds him that the dagger could grant him the power to reverse death; instead, he stabs himself, and his body is possessed by Set. Set goes to Ahmanet as he begins to take over, but Nick looks at Jenny's dead body and remembers both her and Jekyll's words. Nick regains control and uses Set's powers to extract Ahmanet's life force, killing her, and Jenny is revived. Struggling against Set and knowing that Prodigium is coming for him, Nick says goodbye to Jenny and vanishes.
As Ahmanet is sealed back in her sarcophagus, Jenny and Jekyll wonder whether Nick, now fused with Set, will use his powers for good. Nick returns to the desert and resurrects Chris. The two go on an adventure, hoping to find a cure to remove the curse.
