Iraq military logistics veteran Mark Tevis joins cripple grandfather George, who finally pursues his lifelong dream: digging up in a Californian desert the film set for legendary epic films director Cecil B. DeMille's Biblical 'The Ten Commandments', which he saw as young son of the location scout. They find a box containing George's childhood treasure, including an amulet. This unleashes a curse from early Phanaonic times, liberating the monster henchman of the evil god Seth, who starts by ripping off George's arm, a fatal wound. Expedition leader Alice hires Mark to speed up the emergency dig, but the entire crew is terrorized by the curse. Her nearly-divorced husband Jesse Carter deciphers the atypical hieroglyphs but is possessed himself.
