Late on Christmas Eve, decorated SAS officer and Egyptologist Jack West Jr is about to make a discovery that could rewrite history.

In the ancient Temple of Dendur, housed in New York's Metropolitan Museum of Art, a legendary weapon has lain hidden for millennia.

But Jack is not the only person who knows about the artifact's existence. As Jack examines the temple in the deserted museum, he is watched by a mysterious figure. A man intent on stopping him at any cost.
