After the plane blows up, I.J. tells his companions to get passage on a ship, and he'll meet them in Cairo. So forget any ideas you got about lost cities, exotic travel, and digging up the world. We do not follow maps to buried treasure, and X never, ever marks the spot. We cannot afford to take mythology at face value. Once again, it's quote time.
Same rules apply.
Give I.J.'s response. Aid our own resuscitation. Give the title and author of the book which inspired the film. That's what my ex-wife called me. But that doesn't mean you have to like it.
