Source plot synopsis — includes the ending
In 1999, Richard's granddaughter Sam Turkel continues where he left off. Sam, Brad, Burke, and another member of the team break into Talos' burial chamber and see a sarcophagus suspended from the ceiling. Burke falls to his death after he reaches for an amulet, while Brad has a seizure while experiencing Talos' past atrocities.
Nine months later, a power cut occurs before Talos' sarcophagus is going for an exhibition in which it is broken open. Later, a foreigner is killed and his eyes removed. Detective Riley is assigned to the case and believes the killer will strike again. Later, Talos kills several people and removes different organs from different victims. Riley approaches Sam as he thinks Brad is a prime suspect, while she explains the core of Talos' myth to Riley: Talos directed that his followers remove his body parts, and they believed he would someday be resurrected to reclaim them, gaining physical perfection and immortality.
Later, Brad is arrested and tells Talos' history to Riley: Talos was exiled from Greece for sorcery and came to Egypt, where he fell in love, and in a pagan ceremony, married the Pharaoh's daughter, Nefriama. All who opposed him were struck with disease or tortured into believing his theology, so the Pharaoh ordered him dead. To save Nefriama from death, the Pharaoh told her about Talos' upcoming execution, and she, in turn, told Talos. When the Pharaoh's army reached Talos' chamber, they saw Nefriama eating Talos' heart. The followers of Talos were all put to death, including Nefriama. Riley guesses that the murder victims are reincarnations of the Pharaoh's followers. Brad believes Sam is Nefriama's reincarnation and killing her is the only way to stop Talos, who plans to be reborn when the planets align. Brad further explains that part of Talos' curse is that anyone who knows what is going on will be deemed crazy, like himself. After Riley steps out of the interrogating cell, Talos appears and kills Detective Bartone and Brad. A reborn Talos tracks down Sam and captures her.
Riley, now believing Brad, takes part in a ritual where Brad's dead body shows them the possible location Sam might be held hostage: an unfinished construction site. Meanwhile, Sam frees herself and stumbles upon a room where a huge nest made of gauze forms a "cocoon" accompanied by the dead bodies of Talos' victims. As she watches, a horrifying mummy comes out from the cocoon, which quickly evolves into the true form of Talos with only the heart missing.
Riley and his group arrive at the construction site with only minutes remaining before the planets align, and Talos regains his physical immortality. Riley and Claire separate from Butros and Professor Marcus. The latter encounters Talos who manipulates Marcus into killing Butros by strangling her. Meanwhile, Claire falls down and gravely injures her leg, forcing Riley to go forward without her. Professor Marcus finds Claire, who kills him after Talos manipulates her.
Riley finds Sam as Talos intercepts them. Sam begs Riley to kill her, which he reluctantly does. However, Riley is revealed as the reincarnation of Nefriama and it was his heart that Talos wanted, using Sam to lure him. Claire appears and takes out Riley's heart which Talos assimilates within himself just as the planets align.
The police arrive and pull out four dead bodies along with a now hysterical Claire, with the evidence pointing to her as the killer for the authorities. Elsewhere in London, the newly reborn Talos is shown disguised as Riley.
