In 1127 A.D., a group of English crusader knights capture a large ruby from ancient Egypt and bury it within the tomb of one of their number.
In present-day London, a Crossrail construction crew discover the knights’ tomb and a mysterious man is authorized to investigate the uncovered findings inside the site. In a flashback, the hieroglyphics on a circular mural in the tomb, which date back to the New Kingdom era, tell the story of Princess Ahmanet. She was first in line to succeed her father Pharaoh Menehptre only to be stripped of her birthright when his second wife gave birth to a son. Determined to claim the throne for herself, Ahmanet sold her soul to the Egyptian god Set, who gave her a special dagger to transfer his spirit into a corporeal form. After murdering her family, Ahmanet attempted to sacrifice her lover to give Set physical form, but her father’s priests slew him and mummified Ahmanet, sentencing her to be buried alive for eternity inside a sarcophagus surrounded by mercury so that her monstrous form will not escape the tomb.
In present-day Iraq, soldier-of-fortune Nick Morton and his partner Chris Vail accidentally discover the tomb of Ahmanet after staging an airstrike on an insurgent stronghold. Jenny Halsey, an archeologist and former lover of Nick’s, arrives and investigates the tomb, correctly concluding that it is a prison. After extracting Ahmanet’s sarcophagus from a pool of mercury, Nick’s superior, Colonel Greenway, places the sarcophagus on a transport plane, headed to England.
During the flight, Vail becomes possessed by Ahmanet’s power after being bitten by a camel spider while inside the tomb. After attempting to open the sarcophagus, he stabs Greenway and attacks the group before Nick feels forced to shoot him dead. A huge wave of crows then assault the plane, causing it to crash and kill everyone on board except for Jenny, who is parachuted off the plane by Nick.
