[1][2] An elite group of Special Ops soldiers, led by Captain "Mack", are sent by Dr. Elissa Cardell, a CIA operative, to rescue her father, scientist Lee Wesley, from an archaeological dig in the Middle Eastern desert.

Specialist and former hacker "Click"" activates the site's elevator and notices a reference to the "Gehenna Project", which Cardell denies knowledge of.

Suffering hallucinations along the way, they find Duncan trying to open a sealed room, before attacking them and forcing the team to shoot him dead.

Fulton reveals that the "Gehenna Project" is a self-destruct protocol for the site, and realizes that, with Click's unintentional help, Cardell has activated it, leaving the soldiers only fifteen minutes to evacuate.

Fulton, Mack, Cardell, and Click make it out, but Hammer is trapped inside and sets off his grenades, killing himself and most of the possessed scientists attacking him.

Mack, Cardell, and Click arrive at the area where they encountered Duncan and finally find Wesley, who is possessed but without the tell-tale boils.

Cardell stands over Wesley and sets his soul free by taking the Nephilim into herself, then refuses to go with Mack, because saving her father was her only goal.

Now he puts those memories to rest and embraces his new purpose in life: as a new soldier in the ancient war between God and the Nephilim.
