The stranger could be insane. Or he just might be our salvation. Archaeologist Annja Creed is more than curious when a decrepit, ancient-looking man visits her, claiming the end of the world is near. The stranger spins wild tales and speaks as if he actually knew King Arthur. But, strangest of all, he insists that Annja is the only one who can stop the horrible event that is about to happen. When Annja's mentor and friend Roux goes missing, she quickly realizes there may be something to the stranger's stories. Making her way through the dark and violent underbelly of Istanbul, Annja must find her missing friend and the Holy Grail before the relic gets into the wrong hands. She may not fully believe the fate of the world is on the line, but she doesn't really want to die fi nding out.
