 Suspecting that he is somewhere in a temple under the Great Sphinx of Giza, he travels through the dark in an attempt to find an exit, following what he believes to be a draft from outdoors.Instead, he discovers that he has actually been heading further underground, eventually falling down a flight of stairs and landing in a large ceremonial cavern.There he witnesses an army of half-man, half-animal mummies, led by the ancient Egyptian pharaohs Khephren and Nitokris, leaving offerings to a hippopotamus-sized, five-headed, tentacled beast that appears from a hole deep in the hall.
