Archaeologists in egypt accidentally reawaken Norrzug the Iron Lion, a gargantuan sphinx-like monster that once served as the guardian of the ancient city of Amon-Ra. H.E.A.T. discover from ancient texts that the people of the city deliberately rusted the creature to stop its rampage after it turned on them. Now the team must find a way to repeat the feat before this mythological terror devours every last drop of oil in the Middle East.
